■ Edwin Cras is Managing
Director of the satellite uplink
station CASTOR. He is an
enthusiastic satellite DXer
that has been reading TELE-
satellite for many years. “My
first satellite dish was a 1.5-
meter antenna that I installed
in 1990.” Today he uses a
motorized 2.0-meter antenna
at home. He absolutely enjoys
being at CASTOR and working
with all those large dishes
every day; it’s something that a
private satellite DXer can only
dream of.

as a customer that wants to provide their

3 service.” For this customer CASTOR pro-
vides the uplink and downlink Internet
connection not only for their internal op-
eration but also for the public Internet.
“Other similar customers are mining com-
panies or oil companies that want to link
all of their branch offices together.” This
business segment makes up about 50%
of CASTOR’s total sales. Edwin Cras is ex-
pecting that this will increase to 70% by
2013.

CASTOR has an ideal location in the
flatlands of northern Holland: “We can
see all the satellites from 70.5E to 55W.”
Their Burum location is just one part of
CASTOR. “We also operate another up-
link station in Hilversum south of Amster-

here. The satellite beacon signal receiver
is at the top. In the middle is the control
system for the antenna with a display of
the actual value of the antenna (at the top
of the display) and the desired value (at the
bottom of the display) of the antenna for,
in this case, the NSS-12 satellite. The LNB
controller is at the bottom. If an LNB should
fail, this system automatically switches
over to the spare LNB.

dam.” This location is very active with the
uplink of radio stations. He lists them:
“We have been uplinking for Radio 538,
Sky Radio, Veronica, Slam FM, 100%NL as
well as Arrow Rock and Arrow Jazz since
the early ‘90s.“ But that’s still not enough.
CASTOR is developing another business
sector: “We receive the satellite channels
for IPTV providers who then offer them to
customers via the Internet.” One of them
is the IPTV provider ‘Bouquet Uhuru’ with
TV channels from the Congo that CASTOR
receives in the C-band from the RASCOM
satellite at 2E. Another is the provider
‘Premier Satellite’ with some English lan-
guage TV channels from ASTRA at 28.2E.

From the original seven employees it
has become 14 and CASTOR is involved
in many activities in many different ar-
eas that should allow them to tackle any
future opportunities. “Since we have so
many antennas of different sizes available
to us, we can react very quickly to any re-
quests”, comments Edwin Cras and then
continues, “And because of our inexpen-
sive rates we are very attractive to new
customers.”
