AMSATers, particularly those in the Southern Hemisphere are asked to help find the EARTHWATCH Spacecraft. It was launched from Russia last week and apparently stopped transmitting over Christmas. Rex Richardson of Orbital Sciences Corp. has asked for our help. It is they who are to conduct the thermal vacuum testing for Phase 3D. So, I think we owe it to them to try to help them if we can. The EARTHWATCH spacecraft parameters are as follows: Frequency: 401.5 Mhz Modulation FSK @ 192000 BPS ( I believe it is a burst at a 1 sec rep rate) The Ephemeris sets are as follows: NORAD TWO LINE ELEMENTS: 1. 25123U 97085A 97363.20916818 +.00003168 +0.0000-0 +12102-3 0 00353 2. 25123 097.2987 078.9864 0006224 096.5759 263.6190 15.27335732000717 NAVSPACUR ONE LINE ELEMENTS 1. 25123.5375799.8961343.00663.0006224.2703285.9480360.2702742971229 IF YOU MAKE ANY CONTACT PLEASE RESPOND to Rx Richardson at rexrichardson@oscsystems.com Thanks for your help. 73, Bill Tynan W3XO
