AO-85 Update: Do Not Access While in Eclipse

The auto Safe mode was disabled on June 24 and the transponder was turned on. A few QSOs were made to verify that it would drop with inactivity.

Currently, the battery voltage is very low and it looks like a cell is prepared to give up the ghost. Please do not use the satellite while it is in eclipse, even if you hear it. Operations is not sure what will be usable if and when this cell fails completely.

In the meantime, please send reports to the AMSAT-BB. They are welcome and helpful.

PSAT Successfully Launched on Falcon Heavy STP-2

PSAT2 was successfully Launched at 0630Z on June 25, 2019 on the Falcon Heavy STP-2 mission into a 28 degree elliptical orbit with apogee at 860 km  and perigee at 300 km. The 28 degree inclination makes it difficult to work it over most of Europe but the significant difference in apogee and perigee can make a 15 degree or so elevation difference on the horizon. When apogee circulates to be over the northern hemisphere, then more northern stations can work it. When Perigee is over the northern hemisphere, it can only be seen in Spain and Italy latitudes in Europe, and only mid latitudes in the USA.

This changing apogee dynamic will move earlier each day and two weeks later, will have reversed, and so forth on a monthly cycle or so. Another interesting thing about the orbit is that it is almost time synchronous; meaning that a pass will occur almost the same time every day (though five minutes earlier). But then an earlier orbit will appear an hour and a half earlier every other day. This makes it very easy to do mobile/portable operations without any computer once you hear one pass.

Operating Modes

PSAT2 consists of a number of exciting and unique Amateur Radio Communications transponders:

  •  First is a newer PSK31 29 MHz uplink/UHF FM downlink from Brno  University following on to the original on PSAT.
  •  Second is a Brno SSTV camera that downlinks in the same UHF FM  waterfall as the PSK31 users.
  •  Third is a DTMF grid square uplink and voice/APRS downlink for grid position reporting.
  •  Fourth is DTMF Text messaging (APRStt).
  •  Fifth is APRS text messages up and voice down.
  •  Sixth is a conventional APRS digipeater that will join a number of sister APRS Amateur Satellite transponders.

Currently the HF/UHF PSK31 and SSTV modes are enabled and open to users. But the VHF modes have not been enabled for users and users are requested to keep the uplink clear during on-orbit testing.

PSAT2 is designed for maximum orbit life compared to other similar sized cubesats because it is flying with the maximum allowable mass. Almost a kilogram of lead ballast about 2cm x 8cm x 8cm located in the center of the cubesat constitutes almost HALF the satellite’s mass to give it a high ballistic coefficient to last longer on orbit.

One of the most interesting and unique features of PSAT2 is the new APRStt (Touchtone) DTMF/voice transponder which lets everyone do APRS using any radio with DTMF keypad, not just those with APRS radios. There have been several iterations of the APRStt system in APRS over the years since 2001, but this application will be new in space and will help introduce everyone to this unique alternate APRS capability for use with ANY radio.

Operating Frequencies

  •  APRS Up/Down: 145.825 1200 baud APRS (like ISS,  PSAT, AISAT-1)
  •  DTMF Uplink: 145.980 MHz (Voice confirmation down on 145.825 MHz)
  •  PSK31 Downlink: 435.350 MHz +/- 5 kHz FM (300 mw)
  •  PSK31 Uplink: 29.4815 MHz PSK31 SSB (25 W and omni vertical typical)

PSAT2 Digipeater Aliases

To join the existing APRS satellites on orbit and operate as a seamless constellation, PSAT2 supports the same APRSAT and ARISS generic aliases as the original PCSAT (NO44) PSAT and the packet system on the ISS so that users do not have to change any parameters when using any of these three APRS transponders.

Complete PSAT-2 information is available at: http://aprs.org/psat2.html

The PSAT2 User Manual is available for download at: aprs.org/PSAT2/USER-Operations-Manual.doc

Update: PSAT2 is coming to Northern Latitudes!

After reviewing the orbit, it is somewhat time synchronous, meaning each orbit time (at mid northern latitudes) is just 5 minutes later each night. But then a NEW earlier orbit appears 90 minutes earlier every other day. So, by the 4th of July, PSAT2 first pass will be as early as 4 PM local time in the Northern Hemisphere mid latitudes.

And, the apogee moves rapidly. In just two weeks, apogee will be over the northern hemisphere giving higher latitudes much better access. At launch it was the middle of the night and perigee was in the Northern hemisphere making it only visible for lower latitudes. So, things will improve for Northern Hemisphere… then two weeks get worse, etc.

24 Hour telemetry plots (links to FINDU.COM) are now available on at http://aprs.org/psat2.html.

Chinese Lunar Satellite DSLWP-B and the July 2 Solar Eclipse

On July 2 there will be a total solar eclipse that can be observed from parts of the Pacific Ocean, Chile and Argentina. This provides an opportunity to image the eclipse with the Chinese lunar orbiting Amateur Radio satellite Lunar-OSCAR 94 (aka DSLWP-B). An attempt will be made to image the eclipse with the Inory eye camera on-board, where both the Moon and Earth should appear in the images.

The main interest is to photograph the shadow of the Moon on the surface of the Earth. The camera doesn’t have a large resolution and the Earth will look small in the image, but it will be possible to distinguish the shadow learly.

Because the satellite aims its solar panel towards the sun, the camera on-board DSLWP-B is always pointing away from the Sun. Since DSLWP-B orbits the Moon, the Earth will always be in the center of the camera field of view during a solar eclipse. However, it might happen that the Moon is between the satellite and the Earth thus hiding the view of the Earth.

To see the plans for the attempt see https://tinyurl.com/ANS-181-eclipse and https://tinyurl.com/ANS-181-eclipse-times

ARISS International Delegates Meet in Montreal

This week, ARISS held it’s 2019 ARISS International Face-to Face Meeting of international delegates in Montreal, Canada. During the sessions, Kenwood software manager, Shin Aota presented two Kenwood TM-D710GA transceivers to ARISS Russia delegate Sergey Samburov. A TM-D710GA will be used to replace aging amateur radio equipment on board the International Space Station.

For several weeks, these radios have undergone detailed qualification testing followed by software configuration and verification. With today’s transfer of the radios to ARISS Russia, we are one step closer to an enhanced Amateur Radio system on board the ISS supporting various operations such as SSTV,  oice communication, APRS and a variety of experiments.

European Astro Pi Challenge Winners Announced

Two Raspberry Pi computers, Astro Pi units Ed and Izzy have called the International Space Station home since 2016. ESA Education runs the European Astro Pi Challenge which allows students to conduct scientific investigations in space, by writing computer programs.

A record-breaking number of more than 15000 people, from all 22 ESA Member States as well as Canada, Slovenia, and Malta, took part in this year’s challenge across both Mission Space Lab and Mission Zero.

After designing their own scientific investigations and having their programs run aboard the International Space Station, the Mission Space Lab teams spent their time analyzing the data they received back from the ISS. To complete the challenge, they had to write a short scientific report discussing their results and highlighting the conclusions of their experiments. We were very impressed by the quality of the reports, which showed a high level of scientific merit.

the Astro Pi jury has now selected eleven winning teams, as well as highly commending four additional teams. The eleven winning teams won the chance to join an exclusive video call with ESA astronaut Frank De Winne, head of the European Astronaut Centre in Germany where astronauts train for their missions. Each team had the once-in-a-lifetime chance to ask Frank about his life as an astronaut.

PSAT2 Simple Tracking for Wilderness Mobiles
For those hams wandering in the wilderness, Bob Bruninga, WB4APR says, “You don’t need no stinkin’ computer!” Bob has updated his Mobile LEO tracking site to show graphically how PSAT2 orbit works at http://aprs.org/MobileLEOtracking.html. Bob adds, “It’s easy to remember. Five minutes later per day, but a new orbit an hour and a half earlier every other day. This is approximate but time will tell. “If you are in the wilderness, just monitor 145.825 and when you hear PSAT2, then you can easily guess all orbits in the future.” [ANS thanks Bob Bruninga, WB4APR for the above information.]
