3 History of Amateur Radio Satellites Project OSCAR and AMSAT
4 History of Amateur Radio Satellites Project OSCAR and AMSAT OSCAR 1 Launched 12DEC62 CW Transmitter: 140 mw on MHz transmitting HI Operated 22 days from 12DEC16 to 03JAN62 Re-entered atmosphere on 31JAN62 OSCAR: Orbiting Satellite Carrying Amateur Radio Built by Amateur Radio operators of the TRW Radio Club of Redondo Beach, California A secondary payload ballast for Corona 9029 satellite from Vandenberg AFB, CA. Forged, validated, and pioneered the secondary and tertiary payload concept for spaceflight. Was the 214th object launched into space since the initial launch of Sputnik 1 four years earlier! OSCARs 2, 3, and 4 followed.
5 History of Amateur Radio Satellites Project OSCAR and AMSAT AMSAT (Radio Amateur Satellite Corporation (AMSAT-NA): Established in 1969 by radio amateurs working at NASA s Goddard Spaceflight Center in Washington, DC to assist with OSCAR 5 (AO-05). These days there are many AMSAT organizations: AMSAT-NA AMSAT-UK AMSAT-India AMSAT-Chile AMSAT-DL AMSAT-Japan A loose confederation of organizations that connect with each other to build and operate amateur radio satellites. Join AMSAT!
6 History of Amateur Radio Satellites Project OSCAR and AMSAT How does a bunch of hams get a satellite in space? An Example of AMSAT Innovation: Canadian MOST Satellite MOST: Micro-variability Orbiting Space Telescope Originally designed for geostationary orbit Very expensive real estate AMSAT-NA proposed using low Earth orbit satellite with store and forward data capabilities Reduced size, cost, and increased mission length AMSAT awarded with LEAST: Lots of Extra Amateur Stuff on the Telescope!
7 Amateur Radio Satellites
8 Amateur Radio Satellites The Amateur Radio Satellite Phase System Phase 1: No solar cells (battery-powered only), short-lived, technology test-bed. Must be able to orbit to be classified as a satellite. OSCARs 1-5 Phase 2: Long life using solar cells, communications capabilities, in Low Earth Orbit - AO-85 Phase 3: Long life, more powerful communications, telemetry and command systems. Highly elliptical orbit, usually a Molnya orbit; usually the initial orbit is a geostationary transfer orbit, onboard propulsion systems boosting it to its final orbit. Because of the highly elliptical orbit, the satellite remains over an area for long periods of time, allowing amateurs longer contacts through the satellite. AO11 and AO-40/Phase 3D Phase 4: Amateur satellite in geostationary orbit. Phase 4 amateur satellites have been designed, but not built, though they have received favorable attention. Phase 5: Spacecraft capable of lunar or planetary missions.
9 Amateur Radio Satellites Types of Amateur Radio Satellites: A Function of their Mission Single Channel Narrow FM Voice Repeater: AO MHz downlink uplink/435mhz Split Channel Narrow FM Voice: ISS 144MHz uplink/145mhz downlink Single Channel Narrow FM Digital Store and Forward - 145MHz uplink/435mhz downlink 100 KHz Wide Linear Inverted Transponder: AO MHz LSB uplink/435mhz USB downlink
10 Amateur Radio Satellites Traditional HF Amateur Radio Amateur Radio Satellites Available when bands are open Available when in line of sight Band openings unpredictable Satellites have predictable orbits Range depends on ionosphere height Range depends on satellite height If you can hear it, you can work it If you can hear it, you can work it Requires large antennas Can be worked with as little as an HT Modes depend on band/band plan Modes depend on satellite design Beacons aid propagation awareness Beacons monitor satellite availability General or better license Technician license
11 Amateur Radio Satellites Some Amateur Satellite Language Orbit The path a satellite travels Uplink Frequency used to transmit to a satellite Downlink Frequency used to receive transmission from a satellite Doppler Shift A frequency shift caused by relative motion of two bodies The higher the frequency, the great the frequency shift Footprint A circular area of Earth in which satellite is within line of site Apogee A position when the satellite is at the highest Earth altitude Perigee A position when the satellite is at the lowest Earth altitude Inclination Angle of satellite s orbit in relation to the Earth s equator Ascending Node Satellite passing from South to North Descending Node Satellite passing North to South Keplerian Elements Numerical satellite orbit characteristics that allow you to predict pass times
12 Amateur Radio Satellites Phase 2 LEO Amateur Radio Satellites Orbit the Earth between km usually in a polar orbit Because of altitude, pass time is minutes/4 times a day (ascending and descending nodes) Typically operate 2m/70cm (145MHz/435MHz) bands Often called Easy Sats as the FM satellites are the easiest to work strongest signal wins QSOs consist of call sign and grid square exchanges K5NRK, EM42oj FM: SO-50, AO-85, ISS USB: AO-07, FO-29, AO-73 Digital: APRS: AO-16, N0-45, ISS Packet: UO-22, NO45, ISS, GO-32, MO-46
13 Amateur Radio Satellites Phase 3 Satellites HEO Amateur Radio Satellites Earth orbits greater in altitude of 35,000 km. Allows for pass times of hours Rag chewing satellites Linear Transponders (SSB/CW) over many bands Currently no amateur radio satellites are available in this phase Former: AO-11, AO-13, and AO-40 On-the-Drawing-Board: Phase 4B geosynchronous satellite opportunity on the USAF Wide Field of View spacecraft, with AMSAT-NA/Virginia Tech partnership.
14 How to Work Amateur Radio Satellites
15 How to Work Amateur Radio Satellites Question: What type of Amateur Radio Satellite station do you want to operate? Traditional Modes (uplink/downlink) Mode A: 10m/2m Mode B: 2m/70cm (V/U) Mode J: 70cm/2m (U/V) New Mode Band Indicators: V = 2m U = 70cm L = 23cm S = 13cm C = 7.5cm X = 3cm K = 1.5cm Q = 5mm
16 How to Work Amateur Radio Satellites Some Answers: There are all types of Amateur Radio Satellite station configurations. Traditional stations are mode U/V and V/U either base or HT Satellite tracking software configured to azimuth/elevation rotator Can down convert other frequency signals to 144 MHz loss!) - Receive at 2.4 GHz and down convert to 2M (avoid line Recommendation: Start with Easy Sats using an HT and Arrow Antenna
17 How to Work Amateur Radio Satellites An Easy Sat Station Requirements Dual Band HT (144MHz/435MHz) Arrow Antenna Satellite Tracking Software (I-Phone application or WWW access) Sense of Humor Patience and Desire Recommended Satellites: AO-85 and SO-50
18 How to Work Amateur Radio Satellites An Example Pass: Be ready for the pass plan and enjoy as things happen quick Satellite Operator Rule: Adjust for Doppler shift via the downlink From high to low frequency shift like a train Most HTs can adjust only 50 khz segments Let the satellite signal be your guide Listen only for a few passes. Understand what is going on. You will begin to hear regular calls every pass. They are your target You are in Mississippi! Then try to make a contact with one of the regulars. Practice before the pass on your QSO: N5JGK, K5NRK, we are in EM52, Mississippi, copy? K5NRK, N5JGK, thanks for EM52, we are DO12, you re 5/9, 73s
19 How to Work Amateur Radio Amateur Radio on the InternationalSatellites Space Station (ARISS) Some Frequencies: Voice: Uplink: MHz FM Downlink: MHz FM Voice Repeaters: Uplink: MHz FM Downlink: MHz Uplink: MHz FM w/ 67.0 PL Downlink: MHz FM Uplink: MHz FM Downlink: MHz FM VHF Packet/APRS: MHz FM SSTV: MHz FM
