Ham radio satellite activation of Berry Islands, Bahamas

Caribbean IslandSteve M1ACB, Rob M0VFC and John M0IDA will be active on the FM and SSB amateur radio satellites from Berry Islands in the Bahamas.

The trio plan to operate from March 4-10 and will be using hand-held antennas. Since the FM satellites will only cover part of the USA they’ll also be using SSB on FO-29 to reach the British Isles and Europe.

They will be operating from Little Harbour Cay in the Berry Islands, IOTA NA-054, Grid Square FL15do.

Nayif-1 Launched

ISRO PSLV-C37 Launch at 0358 UT February 15, 2017

ISRO PSLV-C37 Launch

The Indian Space Agency ISRO successfully launched the amateur radio satellite Nayif-1 along with 103 other satellites, a record for a single launch. The PSLV-C37 lifted off from the Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh at 03:58 UT on Wednesday, February 15, 2017.

Nayif-1 started transmitting about an hour after launch and radio amateurs in the west of the USA reported the first signals. The first frame of data received at the Data Warehouse was from Christy Hunter KB6LTY. Telemetry data was also received by WA6FWF, KA7FVV, WC7V, NC7V, K6FW, KE7QPV, WA9ONY, W5PFG, KK6AYK.

Ken Eaton GW1FKY reports he received his first frames of data when the satellite came in range of the UK at 10:07 UT.

The satellite looks to be in perfect health and it was placed in autonomous mode before the end of the first day in orbit. Just like FUNcube-1, this mode has the spacecraft sending high power telemetry when in sunlight and with the SSB/CW transponder active when in eclipse. Already many contacts have been made through the transponder. As expected, the frequency stability of this spacecraft is much better than its predecessors.

The launch provider has published a video of the deployment of the 104 satellites

A new post-launch set of TLE’s has been issued by the launch authority and it can be downloaded from http://amsat-nl.org/download/NAYIF_TLE.txt

Please note that these numbers are not based on JSpOC observations so we do not yet have a valid catalog number.

During the Launch and Early Operation phase (LEOP) of the mission, the Nayif-1 command team have been headquartered at the American University of Sharjah Ground station in the United Arab Emirates. They have been very grateful for all the telemetry received from around the world. It has proven to be immensely useful to the team in checking that the spacecraft is functioning correctly.

Nayif-1 Deployment

Nayif-1 Deployment

Our world-wide network has greatly impressed the many professionals that have been watching our activities. Already more than 100 ground stations are submitting data to the Nayif Data Warehouse. Please continue uploading the data as this will further enhance our knowledge about the spacecraft and the space environment through which it is traveling at 7.6 km/s.

The Nayif-1 Data Warehouse has been updated and now includes the Whole Orbit, High Resolution graphs and the upload ranking. It also includes telemetry details from the ADCS sub-system – this is called the iMTQ and is capable of actively magnetorquing. Over the coming days, we will be further tweaking the warehouse, so bear with us if it is unavailable for short periods of time.

Background
Nayif-1 has been developed by the Mohammed bin Rashid Space Centre (MBRSC) and American University of Sharjah (AUS). The UAE’s first Nanosatellite was developed by Emirati engineering students from AUS under the supervision of a team of engineers and specialists from MBRSC within the framework of a partnership between the two entities, aiming to provide hands-on experience to engineering students on satellite manufacturing.

Nayif-1 Mission PatchThe spacecraft includes a U/V linear transponder and telemetry transmitter. It employs enhanced oscillator circuitry and includes an active attitude determination and control system.

The operating frequencies for the spacecraft are:

Telemetry
145.940 MHz using 1k2 BPSK to the FUNcube standard.

SSB/CW Transponder
Uplink on 435.045 – 435.015 MHz
Downlink on 145.960 – 145.990 MHz

AMSAT-UK and AMSAT-NL are delighted to now be able to confirm that the Nayif-1 1U CubeSat, which has a full FUNcube payload, is now scheduled for launch on an Indian PSLV launch vehicle at 03:58 UT on February 15, 2017. The flight, PSLV-C37, will be carry a total of 104 satellites into orbit.

UPDATE Feb 14: Nayif-1 TLEs for tracking are at http://download.funcube.org.uk/nayif_tle.txt
Join in the Nayif-1 launch day chat on the FUNcube IRC channel, your reception reports are most welcome, see http://irc.lc/freenode/funcube (If you have a Callsign put it in the nickname field)

The 145.940 MHz 1k2 BPSK telemetry beacon, running 50mW output, should activate  at approximately 04:54 UT on Wednesday, February 15 when the spacecraft is heading north over Mexico and the western parts of the US and Canada.

During the Launch and Early Operation Phase (LEOP) of the mission, the Nayif-1 command team will be headquartered at the American University of Sharjah Ground station in the United Arab Emirates. They will obviously be especially keen to have all possible reports of signal reception during this first orbit!

To encourage everyone to take part, there will be a small prize for the stations that submit the first data to the Nayif-1 Data Warehouse. Please help the team if you can.

Nayif-1 has been developed by the Mohammed bin Rashid Space Centre (MBRSC) and American University of Sharjah (AUS).

The spacecraft includes a U/V linear transponder and telemetry transmitter. It employs enhanced oscillator circuitry and includes an active attitude determination and control system.

As with previous missions carrying FUNcube payloads, AMSAT-UK would very much like to receive as many reports from stations around the world, especially during the first few minutes and hours after launch.

There is a mission specific Telemetry Dashboard for this project and this can be downloaded from http://download.funcube.org.uk/Nayif-1_Dashboard_1038_installer.msi  and, in a similar way to the FUNcube-1 Dashboard, this will be capable of uploading the telemetry received to a central Data Warehouse.

Guidance Notes for the installation of the Dashboard, integration with a FUNcube Dongle and the Data Warehouse have been prepared for the Nayif-1 mission. These can be downloaded from https://funcubetest2.files.wordpress.com/2017/02/nayif-1_dashboard_notes_release_1-0b.pdf

A file to test that the Dashboard and Warehouse configuration are working correctly can be downloaded from  http://download.funcube.org.uk/nayif1_testfile.funcubebin

The Data Warehouse is still under final development but can be viewed at http://data.amsat-uk.org/nayif1/

Please note that if you are already a registered user of the FUNcube Dashboard then you do not need to re-register. Your existing details will transfer automatically to the new Dashboard when you run it for the first time.

The operating frequencies for the spacecraft will be:

Telemetry
145.940 MHz using 1k2 BPSK to the FUNcube standard.

SSB/CW Transponder
Uplink on 435.045 – 435.015 MHz
Downlink on 145.960 – 145.990 MHz

Initial operations of the spacecraft will be in a low power “safe” mode where only the telemetry transmitter is activated.

Slow-scan television (SSTV) transmissions are planned from the International Space Station (ISS) on February 13-14, 2017.

The SSTV images will be transmitted as part of the MAI-75 Experiment on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module. It is expected they will use the PD-180 SSTV format.

The MAI-75 activities have been scheduled for the Russian crew on Monday, February 13 from 09:25-18:00 GMT and Tuesday, February 14 from 11:25-16:30 GMT.

Note the ISS transmissions on 145.800 MHz FM use the 5 kHz deviation standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try the wider filter.

The ISS Fan Club website will show you when the space station is in range http://www.issfanclub.com/

Tancredo-1 TubeSat Video

Ubatubasat TeamPaulo PV8DX has released a video describing the new TubeSat Tancredo-1 and showing reception of the 437.200 MHz downlink by Drew KO4MA.

Tancredo-1, mounted in a TuPOD Deployer, was ejected from the International Space Station on January 16, 2017. The satellite is a STEM project built by middle school students at Escola Municipal Tancredo Neves school in Ubatuba, in the state of Sao Paulo, Brazil.

The video is in Portuguese but try enabling the YouTube Closed Caption subtitles and use the Auto-translator to get English.
