RadFXSat/Fox-1B Launch Opportunity Announcement November 2016

AMSAT has been notified by Scott Higginbotham, Mission Manager for ELaNa-12 (Fox-1A launch) and ELaNa-14 (RadFxSat/Fox-1B launch) in NASA’s Launch Services Program at Kennedy Space Center, “The ELaNa-14 CubeSat complement is scheduled to fly along with NOAA’s JPSS-1 spacecraft on a Delta II that will be launching from VAFB on November 15, 2016. Due to a number of CubeSats recently dropping off of the manifest for this flight, a door has been opened, and it is my pleasure to inform you that your respective CubeSats (RadFXSat, GoldenEagle-1, EagleSat, and MiRaTA) have all been
officially added to the manifest.”

AMSAT will begin working with Tyvak, the CubeSat Dispenser and Dispenser Integration Contractor for this flight. Additional news regarding the schedule milestones toward meeting launch requirements will be released as more information becomes available.

In a message sent to AMSAT Vice President Engineering, Jerry Buxton, N0JY, Higginbotham concluded, “Congratulations and welcome aboard!”

Fox-1 Development, Launch, and Frequency Coordination Status at Dayton

During the Dayton Hamvention, AMSAT Vice President Operations, Drew Glasbrenner, KO4MA, and AMSAT Vice President – Engineering Jerry Buxton, N0JY, provided more information about the Fox-1 satellites under development. Buxton, N0JY, says Fox-1A has passed all environmental testing and is integrated into the P-POD deployment canister. “The ‘remove before flight pin’ has been pulled, the doors closed on the P-POD, and everything is aboard the shipping container now en route to Vandenberg Air Force Base in California for launch”, said Buxton.

Previously Buxton had announced plans to incorporate an L band receiver in Fox-1C and Fox-1D. The addition will allow ground commanded selection of the U/v (normal Fox-1 bands) or the new L/v 1.2 GHz (23 cm) mode. Both bands will operate as FM single channel. (See: http://www.amsat.org/?p=4000)

During the satellite operations segment of the AMSAT Forum Glasbrenner provided the details of the uplink and downlink frequencies for the Fox-1 FM cubesat fleet.

Fox-1 Frequencies

                                            Uplink FM (67 Hz tone)     Downlink FM

Fox-1A                                 435.180 MHz                     145.980 MHz

RadFxSat/Fox-1B*              435.250 MHz                     145.960 MHz

Fox-1C*                               435.300 MHz                     145.920 MHz

       1267.300 MHz **               145.920 MHz

Fox-1D*                                435.350 MHz                    145.880 MHz

        1267.350 MHz **              145.880 MHz

* Pending IARU Coordination, If needed, changes will be announced

** U/v and L/v operations switchable by command station,
not operational simultaneously

According to Buxton, the team is planning to have an affordable L band uplink ground station available to amateurs by the time Fox-1C is on orbit.

+ Fox-1A will launch on a NASA ELaNa flight scheduled during the third quarter, 2015 from Vandenberg AFB. Fox-1A is a passenger aboard this launch driven by the schedule of the primary payload. When updates are available with firm dates they will be announced via the ANS bulletins, on the AMSAT web, and in the AMSAT Journal.

+ Fox-1B will fly with the Vanderbilt University radiation experiments expected in 2016.

+ Fox-1C will launch on Spaceflight’s maiden mission of the SHERPA multi-cubesat deployer on a SpaceX Falcon 9 flight planned for late 2015.

+ Fox-1D is a flight spare for Fox-1C. If not needed as a spare it will fly with the University of Iowa HERCI radiation mapping experiment.

+ Fox-1E “Evolution” will carry a Mode J linear transponder. The transponder is planned to be 30 kHz wide and will also have a 1200 bps BPSK telemetry beacon. Launch opportunities are being developed, to be announced at a later date.

Fox-1C and Fox-1D Include L-Band Uplink; Fox-1E Linear Transponder Announced

AMSAT Vice President – Engineering Jerry Buxton, N0JY, announced plans to incorporate an L band receiver in Fox-1C and Fox-1D. The addition will allow ground commanded selection of the U/v (normal Fox-1 bands) or the new L/v 1.2 GHz (23 cm) mode. Both bands will operate as FM single channel.

Rather than adding a complete new receiver, the L band “Project Downshifter” will convert the received L band signal down to the Fox-1 uplink frequency and feed it to the regular UHF receiver on the Fox-1satellite. The design will not require an additional antenna on the satellite because the existing UHF antenna will work for L band receive as well.

In concert with the development of the satellite segment, a new group of volunteers is working on a companion uplink station to convert UHF to the L band uplink frequencies:

+ Bruce Herrick, WW1M
+ Dan Hubert, VE9DAN
+ Elizabeth Schenk, KC1AXX
+ Dave Smith, W6TE
+ Alfred Watts, AF5VH

The team is planning to have an affordable L band uplink ground station available to amateurs by the time Fox-1C is on orbit.

In further news, Jerry announced the plan to construct a Fox-1E “Evolution” variation of the Fox-1 series which will carry a Mode J linear transponder. The transponder is planned to be 30 kHz wide and will also have a 1200 bps BPSK telemetry beacon.

The purpose of the project is to test a design for a linear transponder that could be made available to CubeSat builders as a secondary, or even primary radio payload thus bringing more opportunities for amateur radio in space as well as offering AMSAT’s proven communications skills as a telemetry option.

AMSAT has been approached for a launch opportunity for Fox-1E in 2016, but launch details can not be shared at this time.

Jerry concluded, “It is important that we find additional resources to help the Fox-1 Team with these new endeavors. We are looking for volunteers who have solid RF building and testing experience to work on both the downshifter and the transponder prototyping and construction.” If you would like to help and be a part of the success of Fox-1C/D and Fox-1E, please contact Jerry through the AMSAT Engineering volunteer form page on-line at:  http://ww2.amsat.org/?page_id=1121.
