This document discusses processing and retrieval of telemetry data from unmanned aerial systems (UAS). It provides examples of different types of telemetry data formats from military, hobby and commercial UAS. It then describes an architecture for ingesting large volumes of telemetry data from many UAS into Apache Kafka in a distributed manner using geohashing to partition the data. It also discusses architectures for querying the telemetry data stored in Apache HBase and Apache Solr to retrieve data within spatial and temporal filters like polygons and time ranges.
