Haaps
High Altitude Aeronautical Platforms (HAAPS) are airships, planes, or hybrid craft that operate at stratospheric altitudes to provide wireless communications services. They offer several advantages over terrestrial and satellite systems:
1) HAAPS can use existing mobile devices and benefit from more favorable propagation characteristics than satellites, with path losses similar to small terrestrial cells.
2) A single HAAPS platform can initially provide blanket coverage without the staged rollout needed for ground networks. Capacity is increased by adding platforms, not reengineering the system.
3) Onboard equipment requirements are within the limits of airborne power supplies and amplifiers. Ricean fading improves signal quality over terrestrial Rayleigh fading.
High altitude long operation(HALO)
The High Altitude Long Operation (HALO) network is a broadband wireless Metropolitan Area Network (MAN) consisting of HALO aircraft operating at high altitude and carrying an airborne communications network hub, with network elements on the ground.. It will provide broadband services to businesses and to small offices home offices in an area containing a typical large city and its neighboring towns. To each end user, it will offer an unobstructed line of sight and a free-space like channel with short propagation delay, and it will allow the use of low power low-cost user terminals.
Reusable launch vehicle
This document discusses reusable launch vehicles (RLVs). It begins with an introduction that defines RLVs as vehicles that can be used for multiple missions. The main advantage is lower costs compared to expendable rockets. The history section discusses early concepts from the 1950s and serious attempts in the 1990s by companies like McDonnell-Douglas and Lockheed Martin. The present section notes SpaceX's success in recovering Falcon 9 first stages. Design considerations for RLVs include withstanding high stresses and temperatures during launch and reentry. Stages to orbit discusses single-stage and multi-stage options. Vertical landing and retro-propulsion methods are also covered. Preparing a reused RLV requires extensive inspection and refurbishment of components
Optical satellite communication
This document summarizes the Small Optical User Terminal (SOUT) designed for optical communication between low Earth orbit and geostationary orbit satellites. The SOUT uses lasers for transmission and reception, with integrated transmitters, fine pointing loops to correct for disturbances, and an optical bench. It is compact in size at 200x200x150mm and has the potential to enable high-capacity intersatellite links with advantages over microwave technologies in terms of mass and power consumption.

Introduction to satellite communication
This document provides an introduction to satellite communication. It defines what a satellite is, noting that the first Indian communication satellite was Aryabhatta, launched in 1975. Satellites are classified as either active or passive. Active satellites contain transponders that amplify and translate signals to avoid interference. Passive satellites can be natural, like the Moon, or artificial. The document also summarizes Kepler's laws of planetary motion, including his first law that planets orbit in ellipses with the Sun at one focus, his second law about equal areas being swept in equal times, and his third law relating orbital periods to semi-major axes.
Stealth technology in aircrafts
Stealth technology reduces an aircraft's detection by radar through surface designs and radar absorbing materials. Surface designs aim to deflect radar signals away from the source, while RAM absorbs radar waves. Modern stealth aircraft like the F-35 and B-2 Spirit use curved shapes, buried engines, and radar absorbing coatings and structures to achieve a minimal radar cross-section. Stealth technology is an ongoing effort, as advances in radar threaten invisibility, but it has allowed for improved military surveillance and strike capabilities.
Launching vehicles
A launch vehicle is a system used to launch satellites into stable orbits. It works on Newton's third law of motion, where the exhaust gases ejected from the rocket engine provide an equal and opposite reaction force that propels the launch vehicle upward. Launch vehicles are classified based on their payload capacity and number of stages. India's space agency ISRO has used several launch vehicles over the years of increasing capability, starting with the SLV, then the ASLV, and now predominantly uses the PSLV and GSLV.
GPS tracking in Aircraft
GPS aircraft tracking allows planes equipped with GPS receivers to be monitored in real-time.

Vehicle Tracking and Remote Data Acquisition System using Very High Frequency...
This document discusses a vehicle tracking and data acquisition system that uses amateur ("ham") radio operating on Very High Frequency (VHF) bands. The system tracks vehicle location using GPS and transmits the data via VHF radio to a workstation since GSM networks have poor or no coverage in remote areas. The workstation receives the VHF signals, stores the location data, and displays the vehicle's position on a map. Using amateur radio on VHF bands allows the system to provide tracking and communication capabilities where conventional GSM-based systems cannot function.

Solution
The Air Force should invest in those satellite communications technologies unavailable in the
commercial sector that are critical for military-specific, core communications services; other
technologies and services can be adapted from commercial practice. From the foregoing
discussion these critical technologies are:
• Antenna systems that efficiently direct downlink power to users (even at unplanned locations)
and reject jamming on the uplinks by use of multi-beam, real-time adaptive antenna patterns
• Very high-rate (many gigabits per second) communications for sensor data relay and
dissemination among spacecraft, airplanes, and ground sites; optical communications is the
method of choice
• Onboard processing for jamming protection that despreads and demodulates uplink signals and
routes them to appropriate downlinks, providing interconnection of disparate users (including
packet communications)
The present state of practice for advanced antenna arrays is to use global spot multibeam routing
and switching. However, recent advances on antenna arrays have provided limited adaptive beam
forming. Based on the present development, a 3 Gbps data throughput rate should be achievable
on satellites before the end of the century. It will be necessary to continue shifting the RF
communication band to a higher frequency with wider bandwidth to obtain increased data rates.
Therefore, it is essential to continue to develop the electronics required to send telemetry at a
higher operating frequency.
The use of real-time adaptive beam patterns on up-link and down-link on communications
satellites has been very limited. Today, commercial satellites have multiple beams, but they are
usually fixed in anticipation of a particular orbital location and an intended customer base. For
military communications, neither of these is likely since the theater of operations is
scenariodependent. The ability to create multiple narrow-beam downlinks allows the satellite
transmitter power to be directed only to the intended users, as well as permitting frequency re-
use (important in the crowded spectrum allocations). Both factors result in increased capacity
through the satellite. The ability to create multiple narrow-beam uplinks provides high receiving
gain that in turn allows either smaller earth terminals to close the link or higher data rates to be
transmitted. Substantial reductions in ground terminal costs will result. More importantly,
narrow-beam uplinks can be used to reject interfering sources (jammers) out-of-beam, and,
through combining of multiple beams, to reject jamming sources within a beamwidth. The ability
to do such realtime adaptive antenna beam formation to create very deep, narrow nulls anywhere
within the field of view of the satellite over the very wide bandwidths necessary for AJ
modulation is not something that the commercial sector will develop (c.
Airborne internet by V.DINESH KUMAR KSRCT
This document discusses Airborne Internet, a new type of internet service that provides broadband access via aircraft instead of cables or satellites. It would function similarly to satellite internet but without delays. Several companies are working on projects using high-altitude planes, blimps, and solar-powered planes to deliver high-speed wireless internet from the sky. This Airborne Internet has the potential to overcome limitations of land-based internet and provide broadband access to more remote areas.

This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

HAAPS Technology
- 1. HAAPS TECHNOLOGY Presented By : B.Shashank.
- 2. Contents What is HAAPS ? Why HAAPS ? Main Objective HAAPS Architecture Power Requirements HAAPS Projects Applications Conclusion
- 3. What is HAAPS ? High Altitude Aeronautical Platform Stations (HAAPS) is the name of a technology for providing wireless narrowband and broadband telecommunication services as well as broadcasting services . The HAAPS are operating at altitudes between 17 to 22 kms range in stratospheric layer of the atmosphere. HAAPS are able to cover over 100 kms diameter ,depending on the minimum elevation angle accepted from user’s location. The platforms may be aircrafts or airships(essentially balloons) and may be manned or un-manned with autonomous operation coupled with remote control from the ground.
- 4. Why HAAPS ? It combines most of the advantages of both satellite and terrestrial systems while avoiding many of the pitfalls. Traffic can be linked and switched among multiple HAAPS, Satellites and Terrestrial gateways.
- 5. Main Objective Provision of the bandwidth that can support services like multimedia applications (telephony,TV,High speeed internet etc.,..) Ability to operate in a high frequency band on the radio spectrum. Provision of increased capacity for terrestrial telecommunication networks ,either by supporting more users/cells without degrading performance or by providing greater bandwidth.
- 9. Power Requirements Solar powered aircraft must be capable of continuous flight. Energy must be collected and stored at day to both power the aircraft and enable to fly throughout the night. The air craft power system consists of photovoltaic cells and a regenerative fuel cell. The main advantage of this method is that it eliminates the need to carry fuel and to extract and compress air at altitude.
- 10. Transmission and Coding Techniques WRC-97 had announced frequency bands for HAAPS in around 47 GHz(downlink : 47.2 -47.5 GHz and uplink : 47.9-48.2 GHz). A very good approach is the use of adaptive coding and modulation based on channel condition schemes. Three modulation schemes were examined for low, medium and high data rate applications as GMSK,16-QAM and rounded 64-QAM respectively.
- 11. Various HAAPS Projects HAAPS have been proposed using both airship and aircraft technology. 1.Airship Technology i. Sky station ii. Sratsat iii. Stratospheric Platform system from Japan 2.Aircraft Technology i. Halo-proteus ii. Sky tower iii. Heliplat
- 12. Sky station Sky station is the name of an airship system planned by the US company “Sky Station International”. Data rates for fixed services are 2 Mbps for uplink and 10 Mbps for downlink. Data rates for mobile services are 9.6 -16 Kbps for voice and 384 Kbps for data. Cost of the project for a worldwide infrastructure is estimated as $2.5 billion.
- 13. StratSat Startsat is an airship system planned by the UK based company “Advanced Technology Group” for both civilian and military applications. It is steered by by means of contra-Rotating Coned Rotor mounted on a tailcone at the rear of the envelope as part of a compound propulsion system. This unit provides longitudinal thrust (to counter stratospheric winds) and the lateral force(for manoeuvring) to enable the airship to hold station within a 1km cube.
- 14. Stratospheric Platform System from Japan It is planned by the Wireless Innovation Systems Group of the Yokosuka Radio Communications Research Center in Japan .
- 15. Halo-Proteus
- 17. Advantages HAAPS don’t require any launch vehicle. Once a platform is in position ,it can immediately begin delivering service to its area without any global infrastructure. Provides a higher frequency reuse and thus higher capacity than satellite systems. Each platform can be retrieved , updated and relaunched without service interruption. They are powered by solar technology and non-polluting fuel cells.
- 18. HAAPS Issues Light weight. Wind Factor. Safety. Cost.
- 19. Conclusion HAPS will be deployed together with terrestrial and satellites elements to provide another degree of flexibility for system deployment that can be easily adjusted to the needs of the network operators and users’ traffic demands HAPS will play a complementary role in future mobile system infrastructure e.g. consisting of W-LAN, cellular, and satellite mobile systems to ease the deployment and roll out of the 3G and beyond 3G services
