Alan, BA1DU


The CAMSAT XW-2(CAS-3) cluster launch of 9 or more amateur radio satellites is CAS3Ascheduled for 23:00Z on September 18th, 2015, or late afternoon/early evening Friday night in the US. The launch is on the maiden flight of the Long March 6 vehicle, from the Taiyuan launch complex.

Satellite separation is planned for 23:15:14 UTC, and the first orbit has the cluster passing over the central US at approximately 00:05Z – 00:23Z XW-2 1st pass19SEP2015.

AMSAT-NA, AMSAT-DL, and Virginia Tech Announce Potential Phase-3E Opportunity


AMSAT-DL depiction of the Phase 3-Express (P3E) satellite in 2005-2006. Changes in the antenna configuration are planned in 2015. The rocket motor and propellant tank will not be needed on the proposed launch opportunity.


The P3E spaceframe will have room for scientific and amateur radio payload. Bdale Garbee, KB0G, is shown with the spaceframe at AMSAT-DL in 2005.

Virginia Tech has approached the US Government to fly the Phase 3-E space frame into High Earth Orbit (HEO) in order to support scientific payloads as well as serve as an amateur radio satellite.  During the AMSAT-DL Annual Meeting on 4 JUL 15, the AMSAT-DL membership approved the concept, agreeing to allow the Phase 3-E space frame that is currently stored in Germany to be shipped to Virginia Tech in the USA for further construction, testing and preparation for eventual launch to HEO should the US Government formally agree to fund such a mission.

Should the project move forward, AMSAT-NA will apply for frequency coordination from the IARU Satellite Advisor and satellite licensing from the FCC as the satellite’s initial operator.

Stay tuned to the AMSAT-DL Journal, the AMSAT-NA Journal, and the AMSAT-NA News Service for further developments and details as they become known.

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:

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.
