Chang’e 5-T1 and new 1.8m dish online
New spacecraft and new dish were tested this weekend. The spacecraft is the Chinese Chang’e 5-T1, an experimental unmanned lunar mission that was recently launched by the CNSA. The dish is a 1.8m Prodelin offset and is inverted for ease … Continue reading

ISEE-3 Frequency Drift Measured
Based on the latest Horizons update by JPL (based on Arecibo observations) I have measured the frequency drift of the spacecraft TX frequency (transponder A RHCP). It appears to be drifting upward at a rate of 3.3 Hz per hour. … Continue reading

ISEE-3 Signal Getting Stronger
Each day the signal from the old but reliable ISEE-3 spacecraft gets stronger and stronger. I have updated the tracking software to log the signal strength over time. It’s also very easy to see the signal without averaging as shown … Continue reading

ISEE-3 (ICE) Spacecraft Detected
ISEE-3 (ICE) Spacecraft was detected today using a 1.2m dish at 2270.390831 MHz. The signal at this frequency was also simultaneously detected and confirmed by Paul over at UHF-Satcom. The detection was accomplished by integrating multiple FFTs with the spacecraft … Continue reading

LRO on S-Band
The Lunar Reconnaissance Orbiter (LRO) is a nice S-Band (2271 MHz) signal coming from the moon to calibrate your dish. This is especially helpful if you need the accuracy for even higher frequencies where the beam-width is narrower. Below is … Continue reading

Lunar Reconnaissance Orbiter
Here is a quick look at the Lunar Reconnaissance Orbiter (LRO) signal. Even though NASA is shutdown as part the US government shutdown, there is still a good signal coming from the LRO. I was doing a quick 1.2m dish … Continue reading
