CAS-9 XW-3 launch Dec 26 2021

CAS-9 XW-3

Updated info 22 dec from Alan Kung, BA1DU:

Hello OM,
The CAMSAT XW-3 (CAS-9) amateur radio satellite will be launched at UTC 03:11:31 on 2021-12-26 , and will be deployed at 98.858° east longitude and 28.413° north latitude at UTC 03:35:58, location close to Western Australia.

Radio amateurs will receive CW beacon and GMSK telemetry signals approximately 38 seconds after the satellite is separated from the launch vehicle, and then the linear transponder will be put into use after approximately 49 seconds.

Attached is the launch schedule and the Two-Line Orbital Element file.



73!
Alan Kung, BA1DU

This is an example how a pass can look like over north NA and EU:


According to info from ANS-353 and BA1DU, Alan Kung, CAMSAT XW-3(CAS-9) amateur radio satellite will be launched by Chinese CZ-4C Y39 launch vehicle on December 25, 2021 from the Taiyuan Satellite Launch Center in China. XW-3(CAS-9) satellite will be piggybacked on the rocket with primary payload ZY-1(02E) satellite.

The satellite orbit is a circular sun-synchronous orbit with an altitude of 770.1 kilometers and an inclination of 98.58 degrees, the running cycle is 100.14 minutes. The functions of XW-3(CAS-9) satellite include UHF CW telemetry beacon, GMSK telemetry data transmission, V/U mode linear transponder, a visible light band space camera and an experimental thermoelectric generator for high school students. After the satellite completes the in-orbit test and works normally, the space camera photo download will be open to amateur radio enthusiasts all over the world.

When the relevant remote control command is received by the satellite, the GMSK telemetry channel will be used to downlink the photo storage information and photo data, and the telemetry data will stop sending at that time.

XW-3(CAS-9) satellite adopts a 6U CubeSat structure with a mass of about 10kg, an onorbit envelope size of 340.5×121.76x998mm with four solar array panels and a threeaxis stabilized attitude control system is used, long-term power consumption is about 15.2 Watts.

Technical specifications:
● VHF antenna: 1/4 wavelength whip antenna
● UHF antenna: 1/4 wavelength whip antenna
● CW telemetry beacon:
Frequency: 435.575MHz RF power: 20dBm CW rate: 22wpm
● GMSK telemetry:
Frequency: 435.725MHz RF power: 23dBm Data rate: 4800bps
● V/U mode linear transponder:
Uplink frequency: 145.870MHz
Downlink frequency: 435.180MHz
RF power: 20dBm Bandwidth: 30kHz Spectrum inverted

Ham radio satellite on the moon 2022

Source: ARRL and OMOTENASHI Project

Japan’s OMOTENASHI, the world’s smallest moon lander, will have an X-band and UHF communication system, although it will not carry an amateur band transponder. OMOTENASHI is a 6U CubeSat set for launch via a NASA SLS rocket as early as February 2022. It will have a mission period of from 4 to 5 days. The name is an acronym for Outstanding Moon Exploration Technologies demonstrated by Nano Semi-Hard Impactor. Wataru Torii of the Japan Aerospace Exploration Agency (JAXA) Ham Radio Club, JQ1ZVI, said radio amateurs can play a role in gathering data from the spacecraft.

The spacecraft is made up of two separable components, both having independent communication systems — an orbiting module and a surface probe. The orbiting module will take the surface probe to the moon. It will transmit beacon or digital telemetry data on UHF (437.31 MHz). The surface probe — the moon lander — will transmit digital telemetry or three-axis acceleration analog-wave with FM modulation on UHF (437.41 MHz). Transmitter power will be 1 W in both cases.

“If we succeed in receiving the UHF signal from the surface probe, we could know the acceleration data on the impact on the moon and the success of the landing sequence,” Torii explained.

“We already have a station for uplink and downlink at Wakayama in Japan — used as an EME [moonbounce] station. However, if the satellite is invisible from Japan, we cannot receive the downlink signal. So, we need a lot of help from ham radio stations worldwide.” Torii noted that the RF system on the lander only operates on UHF.

The orbiting module beacon will transmit on 437.31 MHz using PSK31. The surface probe beacon will transmit on 437.41 MHz using FM, PSK31, and PCM-PSK/PM.

AMSAT Board of Directors Hears Various Reports

The AMSAT Board of Directors, including newly elected Board members, met via Zoom on Friday, Oct. 29. The day-long meeting included hearing reports on a vast array of projects and initiatives from officers and team leaders:

  • President Robert Bankston, KE4EL, reported that membersip numbers are holding strong, and that recent administrative modernization has reduced overhead costs by more than 30%.
  • Treasurer Steve Belter, N9IP, affirmed the good news about finances. AMSAT is operating “in the black,” and new electronic systems for handling transactions are working well.
  • VP Development, Frank Karnauskas, N1UW, noted that, despite AMSAT’s solid financial standing, additional funds are needed to design, build, and launch satellites. Thus, an effort to apply for grants from philanthropic organizations and corporate sponsors is underway. He also updated plans for the AMSAT Youth Initiative to launch in early 2022.
  • VP Educational Relations, Alan Johnston, KU2Y, reported on the CubeSat Simulator and High Altitude Balloon projects that have been utilized in classrooms and school amateur radio clubs. Volunteers are being sought to develop lesson plans and curriculum for junior high and high school students.
  • David Taylor, W8AAS, AMSAT Delegate to ARISS-International, updated the Board on ARISS school contacts, classroom lessons and hardware kits, as well as the on-board equipment on the space station.
  • Executive Vice President, Paul Stoetzer, N8HM, reported on regulatory issues, including loss of the 3.3-3.5 GHz band and new leadership at the FCC.
  • Vice-President Operations, Drew Glasbrenner, KO4MA, provided a recap of current AMSAT satellites and their status. It was noted that AO-91 and AO-92 are in the “end of life” mode, and users are implored to avoid accessing these satellites during eclipse.
  • Following a recess for lunch, AMSAT Journal editor, Joe Kornowski, KB6IGK, previewed ong-range plans to move the Journal from Adobe Acrobat format to a fully digital format that would allow live links to resources both on and beyond the member portal.
  • Joe Fitzgerald, KM1P, AMSAT Website and IT Manager, updated the Board on the past year’s transition to a new email platform and highlighted the demands for more expertise as web and IT services become more critical to the organization.
  • AMSAT Contests and Awards, and the AMSAT Store, are both managed by Bruce Paige, KK5DO. Ways of promoting awards and store items were discussed.
  • VP Engineering, Jerry Buxton, N0JY, reported on future satellite projects:
  • Linear Transponder Module currently being provided to the University of Maine for their MESAT1 to be launched next year.
  • GOLF-TEE is under construction and has been added to a launch manifest, tentatively for summer of 2022. Supply chain issues are impacting construction.
  • GOLF-1 is planned for delivery one year after completion of GOLF-TEE. Much about this and future GOLF satellites will depend on what is learned from GOLF-TEE.
  • Orbital Debris Assessment Regulations (ODAR) complicate the design and licensing of the GOLF 3-U platforms. NASA/FCC assessments assume a worst-case scenario in which everything fails. If everything works, the service life of the satellite is drastically reduced.
  • Current projects are stretching the available human resources, and additional volunteers are needed to assist in the building of satellite hardware.

AMSAT Board of Directors Considers Proposals

At an online Zoom meeting held on Friday, Oct. 29, the AMSAT Board of Directors considered a list of proposals. Adopted were…

  • Resolved, that the Board of Directors authorizes the senior officers to acquire a commercially-built FM satellite, including a launch, contingent on funding being received from external sources covering at least 90% of the total cost.
  • To authorize the creation of a working group to evaluate opportunities for a flight to a High Earth Orbit / Highly Elliptical Orbit.
  • That the President be instructed to create an ITAR/EAR/Open Source policy and that he be authorized to expend up to $10,000 for the retention of legal counsel to assist in the effort.
