RadFxSat-2 is scheduled to launch later this year on the ELaNa XX mission aboard Virgin Orbit’s LauncherOne air-launch-to-orbit system. The satellite carries a 30 kHz wide V/u linear transponder and radiation experiments for Vanderbilt University’s Institute for Space and Defense Electronics.

RadFxSat-2 / Fox-1E Flight Model Arrives at Fox Labs for Testing

On March 31st, the RadFxSat-2 / Fox-1E flight model arrived at Fox Labs in Granbury, TX where it will undergo testing prior to launch later this year on the ELaNa XX mission aboard Virgin Orbit’s LauncherOne air-launch-to-orbit system. RadFxSat-2 carries a 30 kHz wide V/u linear transponder and radiation experiments for Vanderbilt University’s Institute for Space and Defense Electronics.

FoxTelem Version 1.06 Released

​I am releasing version 1.06 of FoxTelem today.  This release addresses several defects and instabilities in FoxTelem 1.05 and earlier.  It also introduces a new Earth Plot that allows any telemetry value to be plotted as a heat map against a map of the earth.  For more details about the Earth Plot and some example plots, you can read a quick tutorial that I have written here:
http://www.g0kla.com/workbench/2018-01-26.php

As always, let me know if you see any issues or log them on Github at https://github.com/ac2cz/FoxTelem/issues

KEY CHANGES
~~~~~~~~~~~
* EARTH PLOTS allow you to plot any telemetry value as a heat map on a map of the earth
* Allow graphs and telemetry results to be searched with UTC dates and for ranges of uptime/dates
* Allow stepping through the telemetry with up/down arrows
* Prevent hang when decoder starts if FCD returns an error
* Fixed bug where TLEs were not updated in the name is changed in the spacecraft settings window
* Fixed crashes introduced in 1.05 release
* Display all HERCI High Speed payloads when Raw Byte Payloads shown.
* Fix bug where missing TLE disables spacecraft from being tracked at all
* Fixes bug where DDE connection to SatPC32 fails with European decimal point format
* Add MPPT calibration values for Fox-1D
* Improved the RF signal measurements
* Improved the Find Signal algorithm
* Space graph labels more evenly
* Put the spacecraft tabs in FoxId order

And many other bug fixes. Full list of changes here:

AO-92 Commissioned, Open for Amateur Use

On the 03:25 UTC pass on January 26, 2018, AMSAT Vice President – Engineering Jerry Buxton, N0JY, announced that AO-92 had been commissioned and formally turned the satellite over to AMSAT Operations. AMSAT Vice President – Operations Drew Glasbrenner, KO4MA, then declared that AO-92 was now open for amateur use. Audio of the handover and first operational pass can be heard here:

 

Initially, the U/v FM transponder will be open continuously for a period of one week. After the first week, operations will be scheduled among the U/v FM transponder, L-Band Downshifter, Virginia Tech Camera, and the University of Iowa’s High Energy Radiation CubeSat Instrument (HERCI).

Schedule updates will appear in the AMSAT News Service Weekly Bulletins and will also be posted to the AMSAT-BB, AMSAT’s Twitter account (@AMSAT), the AMSAT North America Facebook group, and the AMSAT website at https://www.amsat.org/satellite-schedules/

AO-92 was launched on the PSLV-C40 mission from Satish Dhawan Space Centre in Sriharikota, India on January 12, 2018. For the past two weeks, the AMSAT Engineering and Operations teams have been testing the various modes and experiments on board. Testing has shown that both the U/v FM transponder and L-Band Downshifter work very well. The Virginia Tech camera has returned stunning photos and data from HERCI has been successfully downlinked.

AMSAT thanks the 178 stations worldwide that have used FoxTelem to collect telemetry and experiment data from AO-92 during the commissioning process. The collection of this data is crucial to the missions of AMSAT’s Fox-1 satellites. Please continue to collect data from AO-85, AO-91, and AO-92.
