Hi All,

We have just had a great pass over Sharjah – 32 degrees maximum elevation with 106 frames received and decoded using a AMSAT-UK Turnstile with a FUNcube Dongle and the Nayif Dashboard. We were at ground level standing in a University car-park.

A quick analysis, based on the doppler curve shown on the Dashboard and the Nova predictions using the latest TLEs, suggests that the spacecraft is presently approx 40-45 seconds ahead of the TLE predictions. Whether this is a”fixed offset” or whether this difference will change each day remains to be seen.

Have fun


Graham & Wouter in Sharjah
