HAMTV UplinkK.I. Proposal
HAM Video transmitterOverview
Ham Video in few words
• PI: ARISS community (AMATEUR RADIO on the International Space Station)
• HAM Radio, operating for several years, establishes a half duplex voice-only linkwith crewmembers on the ISS, for educational programs of NASA, ESA and JAXA.
• Ham Video is an enhancement of the Ham Radio program.
• Ham Video is a one-way S-band video / audio transmitter. It modulates avideo/audio signal from a camcorder, transmit a radio frequency (RF) signalthrough one of two L/S band patch antennas (ARISS 41 and ARISS 43) installed onthe nadir side of Columbus.
HAM Video transmitterObjectives
Enhance existing ISS HAM Calls in Columbus
Currently only 10min Ham Radio contacts are possible
With both Ham Radio & Ham Video on orbit and a set of supporting ground
stations: 5-20min video calls could be achieved (ground seeing crew i.e. audio &
video down, audio only up)
Radio Calls ~10min Video Calls 5-20min

HAM Video transmitter Commissioning
Mechanical installation
System should remain deployed continuously(to minimise activity
crewtime)
HAM Video Commissioning
-HAM Video tested sequentially in all configurations (frequencies & bitrates)
-Both Columbus antennas tested
-Wide range antenna (MATERA, Italy - tbc) receiving ~ 8 min visibility
-3 passes planned (2 for sequential configurations tests, 1 functional verification)
- Crew will be in camera FOV as per script (basically filmed performing the equipment protocol)
-Video received by ARISS will be streamed to ESA USOC following commissioning operations
-No use of the Ham Radio
Objectives:- Verify Columbus antenna performances- Identify and validate best suitable HAM Video configuration
HAM Video transmitter Commissioning
HAM Video transmitter envisaged operational scenario examples
HAM TV Operations Examples
-HAM TV contacts as per requested via ARISS (for their education programme or on behalf of an agency) FOV will be specified in event script (typically similar to PAO events)
-HAM TV activations for hours (as long as the camera batteries can last) with digital clock in camera FOV (for ground segment expansion and development)
-HAM TV contacts activated at crew convenience (as for unplanned HAM Radio calls)
Notes: -Ground station involved: initially 5 European stations, they will be expanded by ARISS to a worldwide set-ups.
-HAM Radio operated in parallel for direct communication between crew & ARISS

HAM Video receiverLink Budget Analysis
A radioamateur-grade Uplink Ground Station:
• Camera
• MPEG4/H.264 encoder, 300 kbps output rate
• DVB-S Modulator (FEC ½)
• 10 W HPA, close to the antenna
• Helix antenna (RHCP) with approx. G=14 dBi
• 1.26 GHz amateur band
• Az/El antenna rotator, with tracking software
Upgrading the modulator to DVB-S2
standard will allow some link margin
(+3 dB) and/or longer connection.
A single uplink station will
allow at least 6 minutes ofvideo, for a pass with 50°elevation.
