FUNcube Operations Update

The FUNcube team have announced that AO-73 is now in full time amateur mode

FUNcube-1

As you will know, AO73/FUNcube-1 has been in full sunlight for over one month and has been transmitting continuously high power telemetry for most of that time. This has now been changed to full time amateur mode so the transponder is once again available. With the more stable on board temperatures being experienced, this means that the transponder frequencies are also now more stable.

We expect to leave it in this mode for some weeks so that the team can determine whether or not the currents flowing from the solar panels are having any noticeable effect on the spin period.

FUNcube-2

The FUNcube-2 transponder on UKube-1 continues to be in full time transponder mode. There are occasional breaks in service for a few seconds when the OBC reboots and the other onboard transmitter sends its CW beacon.

FUNcube-3 on Nayif-1

EO88/Nayif-1 continues to perform nominally with high power telemetry when in sunlight and amateur mode when in eclipse.

With their slightly different orbital characteristics it is useful that AO73 is now the early bird, EO88 comes over in the mid morning and UKube provides coverage in the afternoon.

We have been suffering from some network issues in relation to uploading the telemetry from the Dashboards to the Data Warehouse over the past couple of weeks. Apologies for this, but hopefully everything is now stable again. ie fingers are still crossed. Thank you for all the telemetry that you upload.

Like many other teams, we are presently waiting for the next Space-X launch from Vandenberg which is expected to be carrying a number of new amateur payloads, These will provide additional transponder and STEM capabilities for the amateur satellite service. Exciting times ahead.


Ham Radio Satellite List

Amateur / Ham Radio Operator Mineo Wakita JE9PEL has made available a table of all amateur radio satellites in Word and Spreadsheet formats

Also available is a Doppler.sqf file for use in the SatPC32 satellite tracking software.

ExseedSat Ham Radio FM Transponder Satellite

Radio Amateur Gurudatta Panda VU3GDP has been discussing with the Media his involvement in the ExseedSat CubeSat built by an eight-person team at Hyderabad-based Exseed Space Private Limited co-founded by Ashhar Farhan VU2ESE

ExseedSat carries an amateur radio FM transponder and APRS digipeater and is expected to be launched by SpaceX towards the end of 2018.

This satellite will serve the ham or the amateur radio community. As a result, it will be of great help during natural calamities, when conventional communication services get disrupted.
— Gurudatta Panda VU3GDP

After the launch, the artificial satellite will be on a polar orbit with two passes over India everyday. The public will be able to receive this artificial satellite beacon on 145.900 MHz FM using a TV tuner and USB dongle, Mr. Panda added.

Farhan said the eight-member team involved in construction of the small private satellite involved four technocrats and four managerial staff members.

He and Exseed Space co-founder Ashhar Farhan VU2ESE were the communication engineers who played a key role in building the satellite.
