*AMSAT Phase4B Project Specficiations:*
- SDR-based 5 & 10 GHz amateur satellite payload being designed to take
advantage of geosynchronous launch opportunities
- Rideshare established on the US Air Force Remote Sensing Program
Office Wide Field of View (WFOV) geosynchronous satellite being designed by
Millennium Space Systems
- Software-defined radio (SDR) payload from Rincon Research Corporation
*First Responder Applications:*
- Resilient assets allow for 24/7 coverage for amateur radio
communications
- Trained operators mobilize to disaster areas to provide emergency
communications support
- Support from FEMA and the American Radio Relay League (ARRL)
Keep an eye on this. Its a Geo Stationary Sat with Ham Radio on board. It
will have data links and is designed with ECOM in mind.
Just thought I would mention it.
73!
