From: Radu Barza Date: 2005, Oct 30, 3:18 Thank you very much for your help until now! I hope everything is OK with SSETI Express. Please let us know if we can help you somehow. It seems we have a serious situation in Wuerzburg, Germany: due to the extremely unfavorable weather conditions in Wuerzburg (heavy clouds and very thick fog, with visibility sometimes less than 10 m), we were not able to decode much of the sensor data from UWE-1 during the last two passes over our ground station. We have already prepared a list with new equipment we need for the GS, but it might take a while to get it, as 1.Nov.2005 is a national bank holiday in Germany. We are able to send commands to the satellite and we can receive the answers, but the signals we received were S2-S3 level on our S-meter. The last reliable data we have are already 30 hours old. We would urgently need some beacon data in order to characterize the status of our subsystems and decide how to continue the mission. As you already know, UWE-1 is sending one beacon every 60[sec] on 437.505+- MHz, 1200baud AFSK. One beacon is 33 bytes long and you can find attached an example about how to decode part of the beacon data (in case you want to do it by yourself). We would be very happy to receive also raw (.hex) data, we can decode them here. Please send the data to: cubesat@informatik.uni-wuerzburg.de Thank you very much! Please forward this email to everyone able to help us with some new data. You can find attached the newest TLE data. As far as I understood from our ground station team, they have always used the first ones. Thank you very much for your support!

We are very happy to see that the satellite is in a stable condition and all subsystems are working at nominal performance. The weather in Wuerzburg (Germany) is getting better (still very cloudy, but less fog) and we could already establish a good bidirectional communication link to the satellite. Probably on Wednesday we will get some new equipment for our ground station and we believe we can avoid this kind of unpleasant situations in future.

Regarding your latest posting of NORAD and SpaceTrack TLE associations with specific spacecraft, it seems clear that neither list is completely correct. Our collective observations yield a high degree of confidence that Xi-V is Object-F and RS-25 (and therefore MOZ.5/SAFIR/RUBIN 5 and the spent 3rd stage) is either Object-A or -D (which are still too close to resolve). With a little less confidence our observations associate UWE-1 with Object-C. SSETI Express shut down before it was possible to associate it with an object number. We have no way to observe SINAH-1. nCUBE-2 has not been heard and may -not- have separated from SSETI Express. I asked SSTL if they have successfully associated TOPSAT and BEIJING-1 with object numbers. No answer yet. I asked an acquaintance to try to get at least minimal radar cross-section data from NORAD which may help. The data will be substantially different for the 3rd stage vs. TOPSAT and BEIJING-1 vs. CubeSats. No answer yet. Back on UWE-1, it appears we are copying packets via the weak signal only when it is at high elevation (and therefore short slant range and low path loss). I have been comparing TCA times (Time-of-Closest-Approach - and therefore highest elevation) with our observations to improve confidence that UWE-1 is Object-C. I try to keep up with all this in my CubeSat web page at http://showcase.netins.net/web/wallio/CubeSat.htm TNX es 73 de Ralph Wallio, W0RPK http://showcase.netins.net/web/wallio/ ---------------------- JE9PEL Wakita wrote: UWE-1 Nov 8, 2005 13:45-13:59 UTC 22:45-22:59 JST 437.505 MHz 1200 bps AFSK 81 max elevation Signal level was very strong, S9, around TCA. bottom top ---------------------- JE9PEL Wakita wrote: UWE-1 Nov 9, 2005 14:26-14:39 UTC 23:26-23:39 JST 437.505 MHz 1200 bps AFSK 29 max elevation DP0UWE>DD0UWE-9 [11/09/05 23:34:56] <UI C>: 53 01 1E F0 0F F0 01 F0 10 F0 1F F0 02 F5 75 F5 29 FE 79 FD FC F4 E9 F4 7B F4 DA 02 01 02 1E 03 23 by "UWE-1 Analyzer ver 1.2" ----------------------------------------- 1:Current from solar cells 1.1 Solar cell1: 1.875[mA] 1.2 Solar cell2: 0.125[mA] 1.3 Solar cell3: 2.0[mA] 1.4 Solar cell4: 3.875[mA] 1.5 Solar cell5: 0.25[mA] 2:Temperature 2.1 Main processor: 19.85[deg.] 2.2 Respectively batteries: 16.05[deg.] 2.3 Transceiver: 12.85[deg.] 2.4 Top panel: 7.35[deg.] 2.5 Bottom panel: 12.1[deg.] 3:Voltage 3.1 Battery1: 3.705[V] 3.2 Battery2: 3.58[V] ----------------------------------------- You get UWE-1 signals as: DP0UWE>DD0UWE-9 [11/12/05 10:17:10] <UI C>:.......... 44 50 30 55 57 45 3E 44 44 30 55 57 45 2D 39 20 5B 31 31 2F 31 32 2F 30 35 20 20 31 30 3A 31 37 3A 31 30 5D 20 3C 55 49 20 43 3E 3A 53 01 1E F8 AD FA 86 F1 2C F7 38 F1 AE F5 C4 F5 44 FF 69 FE 4B F5 AC F5 7B F5 A5 01 01 02 1E 01 23 0D 0A This hex data can be received by using "TunaTerm ver 5.3".
