JAWSAT Data

As reported earlier in ANS, the JAWSAT launch (with Amateur Radio's newest satellites) has been postponed until early 2000. This delayed launch timeframe will allow ANS to take a detailed look at each of the new birds - starting with this installment.

When the launch actually takes place, there will be several ham payloads on board including JAWSAT, OPAL, STENSAT, ARTEMIS and ASUSAT-1. Non-Amateur Radio payloads are FalconSat and a picosat named DARPA. The initial planned orbit is sun-synchronous and circular with a nominal altitude of 750-km, 98.39 degrees inclination and a 99 minute orbital period. The launch vehicle is an Orbital Sciences Minotaur, built on a Minuteman-II first and second stage with a Pegasus third and fourth stage.

JAWSAT is actually a multi-payload adapter space-frame that once in orbit will deploy four independent satellites:

ASUSAT-1
a microsatellite developed and built by the students at Arizona State University
OPAL
a microsatellite developed and built by the students at Stanford University (which will subsequently deploy several picosatellites)
FalconSat
a microsatellite developed and built by cadets and faculty at the United States Air Force Academy
OSCE
the Optical Calibration Sphere Experiment, an inflatable, reflective calibration sphere

JAWSAT will also support several other experiments that will remain attached to its space frame. The frame will be separated from the fourth stage after all secondary payloads are released. Experiments include the Weber State University Attitude Controlled Platform, the NASA Plasma Experiment Satellite Test (PEST), and a deployment imaging system (that will image the separation of each payload to be used in the development of automated docking algorithms as well as provide a visual indication of separation). These images will be stored onboard JAWSAT and then downlinked at a later date when JAWSAT itself becomes operational.

After JAWSAT reaches its desired polar orbit altitude of 420 miles, it will be about two weeks before PEST is first powered on. PEST will acquire data for at least a two-month period. Amateur Radio satellite operators will get a chance to contribute to the NASA project by recording the PEST data from JAWSAT; data that will help characterize certain aspects of the ionosphere above the D, E, and F layers (where most high frequency signals are reflected).

Data from PEST can be received using either a G3RUH modem or a GMSK modem. Data rates could be as high as 38.4 kb/s, and will be transmitted on 437.175 MHz and/or 2403.2 MHz. NASA will publish information on what transmitter is active and instructions for sending in the received data so the PEST teams can use it.

If the power budget allows, JAWSAT will also have an analog FM transponder in 'bent pipe' mode.

Stay tuned to ANS for more information on these new Amateur Radio satellites!

ISS Update

The International Space Station's altitude was recently raised by an average of 10 statute miles following two thruster firings using jets on the Zarya module. The result of the orbit-raising burns placed the station in a 245 by 238 statute mile orbit in preparation for the arrival of the Zvezda service module early next year. The orbit raising burns occurred about 45 minutes apart with the first lasting 27 seconds. The second burn, designed to nearly circularize the orbit, lasted 23 seconds.

The new altitude protects rendezvous options with Zvezda, which will rendezvous with ISS first as a passive vehicle - and then the space station will be ground-commanded to remotely dock with Zvezda.

Flight controllers in Moscow also elected to return battery number one to the set of batteries available for electrical usage in an effort to evaluate its health. The battery had been offline for some time when problems were noted in its ability to charge and discharge properly. After operating without problem for a week and a half, battery one telemetry showed the unit no longer discharging properly as designed and it was removed from the electrical bus of the Zarya module. Four batteries remain available for electrical power to Station systems.

Meanwhile, at the Baikonur Cosmodrome in Kazakhstan, Zvezda is undergoing final testing and is basically ready for launch. While awaiting the recommendations of the investigation team on the recent Proton launch failure, Zvezda will undergo some repeat testing on equipment with the time available.

Zvezda, (Russian for Star), will serve as the early living quarters for crews housed on the Station when the Shuttle is not present. It also will provide life support functions and command and control capability for the complex.

he International Space Station continues to operate in excellent shape as it orbits the Earth. Since the launch of Zarya in November 1998, ISS has completed more than 5,995 orbits. Space Station viewing opportunities worldwide are available on the Internet at http://spaceflight.nasa.gov/realdata/sightings/

Charles Harris, WB2CHO/VP2ML, Silent Key

For the second straight week ANS is saddened to report on the passing of one of our own. Former AMSAT member, ARRL staffer and CQ magazine DX columnist Charles 'Chod' Harris, WB2CHO/VP2ML, of Santa Rosa, California, died December 8th. Harris suffered from complications from a severe heart attack he suffered in early November. He was 50.

An ARRL Life Member, Harris was first licensed in the late 1960s. He was an honor graduate of Princeton University and president of the school's Amateur Radio club. In the mid-1970s, Harris ran the ARRL Club and Training Department. An active contester and active DXer, Harris had operated from several exotic locations. He obtained the callsign VP2ML while living on the island of Montserrat in the late 1970s and early 1980s before moving to California.

[ANS extends the sympathy of the entire AMSAT organization to the Harris family at this difficult time]
