Achievement of high-accuracy indication of deviation of satellite vehicle from orbit plane about vertical by gyrocompassing techniques requires either extremely tight vehicle control or data handling in stabilized coordinates; paper develops mathematical model and error relationships for latter approach; two configurations, vertical and horizontal damping, are described, and it is shown that former emphasizes LF horizon sensor and gyro errors, whereas latter emphasizes their HF characteristics; systematic error due to earth's oblateness, if uncompensated, may be dominant and can produce over 0. 1° of error of satellite altitudes of 250 nautical mi.
