Looks like Brazil is reporting some success with imagery reception. Perhaps the stabilization is being reached. Good news indeed! https://t.co/QZlp5NiAwU

Putting together X-Band system #2.
A few pieces from the proverbial junk drawer, a few recent surplus purchases and of course imported @uhf_satcom depol and v4ma feed.
This will give offer a second view to DSN objects when the main system is blocked or pointed elsewhere. https://t.co/pSRBs80Ymi

Nice catch Edgar! Too bad sessions are all done by the time Mars rises here. https://t.co/itCPTNn6tT

MOM was showing quite an activity outburst today. Additional to the usual 10 min emission (16:34 - 16:44) it was emitting 14:36 - 15:33. The frequency shift at 14:53 results from switching from MOM compensation to Mars compensation for a better view of the orbital pattern. https://t.co/OctJase1uv

XHRPT Update
Getting close to releasing XHRPT decoder. Upgraded to now decode MetOp-A/B, FengYun-3A/B/C in addition to the previously supported NOAA-18/19/15 and Meteor-MN2. Here is a short video of a typical pass of MetOp-B AHRPT. The video has been speed up, so … Continue reading

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

JPL Updates ISEE3 Horizon Data
Updated my Horizons data for ISEE-3 today and found this nice note: UPDATE (2014-Jun-23): Trajectory updated to JPL solution #32 (s32), based on 42 coarse Arecibo plane-of-sky angular measurements spanning May 22 – Jun 23 … Upon updating things and … 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

Antenna Tracking Software Updated
I developed this little application a couple years ago to manage shuttle passes for automated s-band reception/recording. I have started using it more for DSN now and so have updated it with some new features. The tracker gets it’s Ephemeris … Continue reading

Mars Orbiter Mission (MOM) Signal Detected
It’s been an S-Band weekend here. Earlier today the Indian Spacecraft MOM was picked up by DF2MZ as well as UHF-Satcom at a distance of 107 Million km! By the time the spacecraft rose over California Goldstone had locked it … 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
