\"XW-2A<\/a><\/p>\n

XW-2A satellite was launched September 19, 2015<\/p>\n<\/div>\n

CAMSAT has worked closely with a Beijing Government aerospace contractor to build two satellites with amateur radio linear transponder payloads. A launch had been planned for March 31, 2017\u00a0from Taiyuan into a 524 km Sun Synchronous Orbit (SSO) with an inclination of 42 degrees.<\/p>\n

Both will carry a 435\/145 (U\/V) 20 dBm (100 milliwatt) SSB\/CW linear transponder, a 2m CW 17 dBm (50 mW) telemetry beacon and an AX.25 4.8 kbps GMSK 20 dBm (100 mW) telemetry downlink.<\/p>\n

The two micro-satellites will also carry optical remote sensing missions. Planned to be 494x499x630 mm dimension regular square shape and approximately 50 kg mass with three-axis stabilization system.<\/p>\n

These frequencies have been coordinated by the IARU Satellite Frequency Coordination Panel:<\/p>\n
