Space Operations History
Sputnik 1- 1957
1958: Minitrack establish at Esselen park
The Satellite Applications Centre had its origin in 1958, when the National
Telecommunications Research Laboratory (TRL) of the CSIR agreed to operate and
maintain a Minitrack station on behalf of the American Naval Research Laboratory (NRL) in
South Africa. South Africa was strategically situated relative to the launch facilities in Cape
Canaveral, and would give early confirmation that a satellite launched from Cape Canaveral
was indeed in orbit.
1960 the start of a Minitrack station moving
towards a STADAN
Apollo 11 Launch
SATAN
1961-1975 Supported NASA missions
During the 15 year as part of the GSFC network “JOBURG STADAN” received more than 8
million minutes of data, tracked 400 000 satellite passes and supported over 250 NASA
launches.
1963: 12M Antenna established
In 1963 a 12m hydraulic X/Y mounted parabolic antenna was installed with 400 MHz and
136 MHz reception and mono-pulse tracking capabilities. Shortly afterwards “S” band
reception and tracking capabilities were added. Two 5 kW 148 MHz transmitters were added
each having its own antenna. At the same time, two hydraulically driven X/Y mounted arrays
were installed. During this time a new building was erected and all telemetry equipment and
activities transferred. A sophisticated triple redundant timing system was installed and later
the first PCM data handling equipment, and digital command encoder.
1963 First parabolic antenna UHF/VHF feed
1975: NASA terminates activities.
NASA ceased operations in South Africa at the end of October 1975. The CSIR then used
the remaining equipment and a core group of personnel to establish the Satellite Remote
Sensing Centre (SRSC) in 1976 for reception of geo-information from satellites.
• 1961 - 1975: Support of NASA missions
• 1975: NASA terminates activities
• 1976 CSIR takes control
• South Africa move towards Earth Observation data
• Meteosat
• Landsat MSS
• Noaa data
• Spot 2
• CNES Partnership

Thank you, and that’s my story.
