Description
NASA's Goddard Space Flight Center issued this interface document, Revision A, in August 1966. It defines the pulse frequency modulation encoding system for the IMP D and IMP E satellites, part of the Interplanetary Monitoring Platform series. An interface document fixes exactly how separate pieces of hardware exchange signals, so experimenters and engineers build to the same rules.
Early sections spell out how the D and E encoding system differs from the one flown on IMP A, B, and C. The telemetry format and data processing rules follow, with four methods for reading out experiment digital words. Separate sections cover analog data, input characteristics, and calibration of the analog oscillator. Sync pulses supplied to experimenters are specified. The closing sections treat circuit design and fabrication, including an expanded evaluation of a MOSFET circuit approach.
