Small Satellite Communication constellations
This page list some miscellaneous small satellite constellations proposed for
communications. Refer to the main tables for small satellite
- Proposal for a 8-12 satellite LEO system by the Russian Federation. The satellites would
weigh 250kg each and would be launched into circular 700km orbit inclined at 76 degrees.
- ECO-8 is an 8-satellite equatorial communications system proposed by the Brazilian space
agency INPE. It is to provide cellular quality wireless, fixed and mobile, voice and data
communication services. The coverage area is equatorial up to ±30° latitude, and the
system will connect to the PSTN. The project is founded by Telebras & Constellation
Communication Inc., and potentially some Southeast Asian partners.
The uplink and downlink rates are 9600bps.

- Proposal for a 30-66 satellite LEO system by the Russian Federation.
- The Australian KITComm pty is planning to provide one-way asset management and tracking
services, including localisation (not GPS based) to an accuracy of 1 km. Whilst they are
initially targeting the Australian market, they are keeping their options open for a
world-wide service. There are to be 21 satellites with 3 on-orbit spares, with the first
launch planned in 1999. They will use the (1.5 GHz) L band for communications. The
spacecraft will weigh 3 kg at an altitude of 2800 km with a 90 degree inclination. More...

- A German proposed Store and Forward system. An attached payload was initially launched ,
but in 1998 a free flyer was launched
- Spacequest has proposed a constellation of satellites for global messaging, tag polling
and vehicle tracking. The proposal is based on the AMSAT microsatellite platform.
- With TEMISAT (Telespazio Micro Satellite) Telespazio aimed to develop a two satellite
microsatellite system for commercial VHF/UHF remote data collection. Launch for the first
satellite was in 1993. Plans called for launch of a second
satellite in mid 1995, but was never launched. The TEMISAT program envisioned 1000 user
terminals and 50 collection centres.
