The Overberg Test Range or OTB (
Afrikaans abbreviationfor "Overberg Toetsbaan") is a rocket launch siteand weapons systems testing facility in the Overbergregion on the south coast of South Africa.
Facilities at the site include missile launch pads, tracking radar, optical missile tracking systems, cinetheodolites as well as use of a nearby military airfield. The layout appears to mirror the testing site at Palmachim, suggesting Israeli input in the design process.cite web

Atomic clockfor accurate timing
* Multiple interfaces including IRIG-B, IRIG-A, a variety of slow codes, pulses as well as PC parallel and serial.
* Sophisticated command and control infrastructure, including a central control center, a mobile control center and a central computer.
The site was notably used for test launches of the RSA series of missiles, including the joint Israeli-South African
RSA-3 Intermediate-range ballistic missilein 1989 and 1990. [cite web|url=http://www.astronautix.com/country/soufrica.htm|title=South Africa|publisher= [http://astronautix.com] ] Development of this military programme was cancelled 1992 however. Testing for the South African civil space programme continued at the site for another year before also being cancelled in 1993.
Since then the facility has been hired out for testing purposes to other countries, including:

Testing at the site focuses predominantly on flight performance rather than the destructive capability of weapon systems. Consequently missile test flights are typically conducted with dummy warheads or instrument packs rather than live weapons.
The following types of tests can be performed:
* Air-to-air tests
* Air-to-surface (land or sea) tests
* Surface-to-surface (land or sea) tests
* Anti-tank tests, including from
* Aircraft performance, carriage and release clearance and
