In order to ascertain the effects of main errors of alt-alt photoelectric telescope on measurement accuracy  orientation error is analyzed.For analyzing optical  mechanical and electrical errors from measured target to telescope picture  we construct 7 coordinates such as:the earth's core coordinate  alt-alt coordinate  etc.  carry through 21 times coordinate transformation  form measuring equation with 26 variables. and we utilize Monte Carlo method to calculate the orientation error  analyze the effects of errors upon pointing. The result indicates that the measuring error standard deviation of alt-alt telescope is minimum value about 10? at the zenith zone. and the deviation increases with the rotation angles of longitude and latitude axes. The model and the method not only can analyze and synthesize the main errors  but also provide a reference to the whole design. 2009 SPIE.

North-finder system is an important application of the inertial technology. It provides true north azimuth information to f all kinds of ground-based equipment. This paper designed a dynamic automatic north-finder based on the modulation output of fiber optic gyroscope (FOG). In this scheme  the sine output signal of the FOG was sampled and disposed  and then the real north of surveyed point on the surface of earth was calculated. The deviation caused by the base tilt was compensated by an accelerator. The output signals of FOG and accelerator were computed combined with the position sampled from increasing encoder by digital signal processor. Successive rotating technique was adopted to modulate the FOG signal periodically. Most of the low frequency part of random gyro drift errors was compensated. The north-finder accuracy was improved compared with the traditional static measuring method. The test result shows the FOG automatic north-finder obtains 2' true north angle accuracies within not more than three minutes  can meet the orientation need of artillery  terrain measurement vehicle  armored car  unmanned drive vehicle  geodetic survey and tunnel exploration.
