Staple-bound official NASA manual for the “Skylab A” mission entitled “EREP Users Handbook,” dated March 1971 and prepared by the Science Requirements and Operations Branch at Houston’s Manned Spacecraft Center. This book, 379 pages, 11 x 8.25, is an instruction and handling manual for use of the Earth Resources Experiment Package (EREP) onboard the Skylab spacecraft. The manual contains the following sections: Skylab Program, Skylab Hardware, Skylab Experiments, Mission Profile, Flight Planning, EREP Data Handling, Crew Activities, Ground Truth, Aircraft Support for Skylab, Proposal Preparation, Requirements Implementation, MSC EREP Organization and Key Personnel, and Skylab Documentation. In very good to fine condition, with some light toning and surface loss to the front cover.
A group of six remote sensor systems (sensing visible, infrared, and microwave radiation) known as the Earth Resources Experiment Package (EREP) was flown on the NASA Skylab spacecraft to furnish data to numerous investigators in the earth sciences and in technology assessment. Inflight sensor performance in three categories (functional, geometric, and radiometric) was evaluated using: ground measurements of surface, atmospheric, and illumination parameters; ground deployment and operation of microwave receivers and transponders to monitor and excite the active EREP sensors; measurement of surface and atmospheric parameters by instrumented aircraft on underflights of Skylab passes; and analysis of the actual flight data. This resulted in identification and correction of anomalous sensor operation, quantization of geometric distortions or aberrations, improvement or confirmation of calibrations, and determination of sensitivity, accuracy, and stability of the sensors.
