    Advanced communications experiments for Spacelab (1975)

    Publication Date: 2019-07-13
    Description: The Spacelab design and mission capabilities appear to provide a practical vehicle for meeting communication experiment needs. Results of recent discussions and numerous contractual activities have conclusively corroborated the potential useful role that a manned laboratory in space can afford to the communications community. Some examples of the experiments that appear presently as strong candidates for early flights on the Spacelab missions of the 1980s are discussed. Particular attention is given to radio frequency interference, bandwidth compressive modulation, laser experimentation, and use of large deployable communications antenna. It can be expected that the Spacelab will reduce the time, risk, and cost for conducting some communications experiments and developing the related space technology.

    Satellites for distress alerting and locating: Report by Interagency Committee for Search and Rescue Ad Hoc Working Group (1976)

    Description: The background behind the congressional legislation that led to the requirement for the Emergency Locator Transmitter (ELT) and the Emergency Position-Indicating Radio Beacon (EPIRB) to be installed on certain types of aircraft and inspected marine vessels respectively is discussed. The DAL problem is discussed for existing ELT and EPIRB equipped aircraft and ships. It is recognized that the DAL requirement for CONUS and Alaska and the maritime regions are not identical. In order to address the serious DAL problem which currently exists in CONUS and Alaska, a low orbiting satellite system evolves as the most viable and cost effective alternative that satisfies the overall SAR system design requirements. A satellite system designed to meet the needs of the maritime regions could be either low orbiting or geostationary. The conclusions drawn from this report support the recommendation to proceed with the implementation of a SAR orbiting satellite system.

    Spacelab communications experiments (1974)

    Publication Date: 2019-08-13
    Description: The Space Shuttle launched Spacelab is planned to provide the communications community with a platform to develop the technology required for NASA's and DOD's missions, and future domestic and international communications satellites in the 1980s. The Laboratory, with a weight carrying capability of 14,500 kg into a low-earth orbit and return to earth, is being planned to carry laser telescopes; large (greater-than 10 meter) deployable antennas; spaceborne receivers to map terrestrial noise sources in a variety of frequency bands, and other advanced technology applicable to the 1980s and 1990s. Spacelab will also facilitate ease of comparative testing between alternative or competing experiments, subsystems and components prior to a commitment to an automated satellite.
