ROCSAT
Taiwanese earth sea satellite. 3 launches, 1999.01.27 (ROCSAT-1) to 2008.10.01 (ROCSAT 2). Taiwan's ROCSAT (Republic of China Satellites) were built for Taiwan's National Space Program Office.

The test satellite series progressed from all-American to all-indigenous satellite components.

Taiwan's first satellite, ROCSAT (Republic of China Satellite) was built by TRW for Taiwan's National Space Program Office. ROCSAT carried a Ka-band experimental communications payload, an ocean color imager experiment to study plankton distribution for fisheries management, and an instrument to measure thermal plasma in the equatorial ionosphere. It was equipped with a small hydrazine orbital adjustment engine.

ROCSAT-2, scheduled for 2003, was to observe and monitor the terrestrial and marine environment and natural resources throughout Taiwan, its remote islands and surrounding ocean. It would also carry a sprite imager to study electrodynamic coupling between thunderclouds and the upper atmosphere. Taiwan contracted for launch of ROCSAT-2 on an American Taurus booster.

On 4 May 2001 Taiwan and the United States on Thursday signed an agreement to produce and launch by the end of 2005 six ROCSAT-3 micro satellites for weather forecasting. Taiwan companies were to be awarded contracts for the major components. ROCSAT-3 was part of Taiwan's 15-year space program launched in October 1991 at an estimated cost of $ 413 million.

Gross mass: 400 kg (880 lb).
First Launch: 1999.01.27.
Last Launch: 2008.10.01.
Number: 3 .

Associated Launch Sites
  • Cape Canaveral America's largest launch center, used for all manned launches. Today only six of the 40 launch complexes built here remain in use. Located at or near Cape Canaveral are the Kennedy Space Center on Merritt Island, used by NASA for Saturn V and Space Shuttle launches; Patrick AFB on Cape Canaveral itself, operated the US Department of Defense and handling most other launches; the commercial Spaceport Florida; the air-launched launch vehicle and missile Drop Zone off Mayport, Florida, located at 29.00 N 79.00 W, and an offshore submarine-launched ballistic missile launch area. All of these take advantage of the extensive down-range tracking facilities that once extended from the Cape, through the Caribbean, South Atlantic, and to South Africa and the Indian Ocean. More...

  • Cape Canaveral LC46 Trident, Athena launch complex. This complex was built as part of the U.S. Navy's Trident II ballistic missile effort at the Cape. Construction was underway in February 1984, and the complex was ordnance-certified in November 1986. Complex 46 supported the Cape's first Trident II test missile launch on 15 January 1987. Eighteen more Trident IIs were launched from the site between 17 March 1987 and 27 January 1989. As Trident launch operations moved out to sea later in 1989, the complex was placed on standby status awaiting special Trident II test requirements. No new requirements surfaced in the 1990s, but the Spaceport Florida Authority (SFA) won $4,890,000 in Air Force grants to redesign Complex 46 to handle small commercial space launch operations (e.g., Lockheed Martin's new LMLV-2 space launch vehicle).
