Quetzal-1 CubeSat – Credit Universidad del Valle de Guatemala
Guatemala’s first satellite, a small CubeSat called QUETZAL-1, was deployed from the International Space Station (ISS) on Tuesday, April 28, 2020.
Its primary mission is to test a sensor for remote data acquisition for natural resource management, which could be used to monitor water quality in inland water bodies.
The satellite is part of the Japanese Kibo cubesat program, a product of the cooperation between, among others, the United Nations Office for Outer Space Affairs (UNOOSA), Universidad del Valle de Guatemala (UVG), and more institutions. The operational frequencies were chosen through cooperation from Guatemalan radio amateurs and the International Amateur Radio Union (IARU).
Downlink 4800 bps GMSK on 437.200 MHz.
The Quetzal-1 project team director is Guatemalan engineer José Bagur, TG8JAV, a graduate from mechatronics engineering at Universidad Del Valle.

Sarah Rogers KI7OOY reports that following the successful launch of NG-13 on Feb 15, the upcoming CubeSat deployment from the ISS is now scheduled for Wednesday, February 19.
This deployment times and frequencies for the CubeSats being deployed on this date are listed in the table below.
As a member of the Phoenix CubeSat team, it would help us greatly to have as much help as possible with tracking our spacecraft following deployment!
For more information on Phoenix’s transceiver characteristics and how you can decode packets from our spacecraft, please see our operations page:
If you have any questions regarding deployment or tracking Phoenix, please do not hesitate to reach out to me.

Several CubeSats are expected to be deployed from the International Space Station into orbit next week, among them are QARMAN and Phoenix.
Amandine Denis ON4EYA of the QARMAN project reports that due to the delays in Cygnus launch, deployments are postponed most likely to early next week, after Cygnus docking. Qarman can’t wait to make the big jump! See https://twitter.com/AmandineOufti
QARMAN will perform experiments on stability during the the orbit phase and measurements of ablation and radiation during re-entry.
Phoenix is a 3U CubeSat developed by Arizona State University to study the effects of Urban Heat Islands through infrared remote sensing. Following deployment, the Phoenix operations team would appreciate as much help as possible with identifying the spacecraft and verifying that it is operational.
Please note that two CubeSats being deployed operate on the same frequency. Both Phoenix and QARMAN share the frequency of 437.35 MHz, and both utilize an AX.25 9600 baud protocol with GMSK modulation. Both CubeSats will also be deployed within 1.5 hours of each other, and will therefore be close to each other in orbit. Please be mindful of this situation, and if you have any doubt about the CubeSat that you are receiving, please get in touch with Sarah Rogers KI7OOY, Project Manager, Phoenix CubeSat, sroger13 [at} asu.edu with any questions or concerns.

The ARISS-UK Team have announced that the Electromagnetic Field 2020 event is to host an ARISS contact during the weekend of July 23-26.
The event will be held at Easton Manor Deer Park, near Ledbury in Herefordshire.
The callsign for the contact will be GB4EMF and the ISS will use NA1SS. More details will be available closer to the date.
Imagine a camping festival with a power grid and high-speed internet access; a temporary village of geeks, crafters, and technology enthusiasts that’s lit up by night, and buzzing with activity during the day. Thousands of curious people will descend on the friendly open space to learn, share, and talk about what they love.
Talks and workshops start at midday on Friday and last until the Sunday evening.
The first public sale of tickets for EMF 2020 will be Wednesday, February 19, at 19:00 GMT. For the full list of ticket sales dates, see https://blog.emfcamp.org/2020/02/14/ticket-sales-dates/

ARRL reports University of Washington’s HuskySat-1 3U CubeSat, launched November 2, 2019, is set to deploy January 31 after the vehicle that carried it to the International Space Station undocks.
Update January 31, 2020: HuskySat-1 is expected to be deployed by Cygnus at 22:30 GMT on Jan 31, the 435.800 MHz beacon should be activated at 23:05 GMT.
HuskySat-1 has remained stowed aboard a Northrop Grumman Cygnus supply vehicle. Within 24 hours after Cygnus’ departure from the ISS, HuskySat-1 and SwampSat 2 will be deployed into orbit. After deployment, HuskySat-1’s 1,200 bps BPSK beacon on 435.800 MHz should be active and decodable with the latest release of AMSAT’s FoxTelem software. HuskySat-1 is expected to carry out its primary mission before being turned over to AMSAT for amateur radio operation.
HuskySat-1 features a 30 kHz wide V/U linear transponder for SSB and CW. The uplink passband will be 145.910 – 145.940 MHz LSB/CW. The downlink passband will be 435.840 – 435.810 MHz USB/CW (inverting). Telemetry will be transmitted on 435.800 MHz, 1k2 bps BPSK with an experimental downlink at 24.049 GHz.
