GPS
The GPS antenna should be an active type of antenna with a gain of at least 26dB and compatible with a 3.3
volt DC supply provided directly by the CTM-200 via the coax cable. The antenna installation should typically
be on an upper horizontal surface of a vehicle or building with a clear 360-degree view of the sky.
Connect a suitable GPS antenna to the port labeled “GPS”. For best performance select a GPS antenna that
supports GPS/Glonass/Galileo(GNSS) constellations.

Satellite (Optional)
The Chameleon CTM-200 “Dual Mode” Gateway features an Iridium Subscriber Unit (ISU) satellite module
(SBD9602) and a mini-PCI express/NGFF form factor cellular wireless module. With the internal ISU,
reports, cmd commands and Packet Assembly/Disassembly (PAD) can all be sent via satellite. The CTM-200
offers remote configuration dual mode features, where It can be set to smart switching, using cellular when
available, and where cellular coverage is marginal, it switches to satellite (resulting in 100% coverage).
