] to 1g 7er are ase che - check clock-A: for attitude (W, PHI Check Check ) and height (BZ) control: if the clock does not indicate repetitions, proceed to next exposure station with flight line shifted in height by an amount (BZ). Camera attitude will be accumulated to the values of (W, PHI) of the previous exposure station. if the clock indicates repetition of loop, it means that the pilot will correct his flying height and camera attitude to the required values. This means that the aircraft proceeds to next exposure as if the previous one has ideal attitude and correct flying height. Clock-B for drift (BY) and (K) correction: if the clock does not indicate repetition of loop-B for these corrections, proceed to the next exposure station as if the flight line is shifted in plan by this amount of (BY). The camera swing of the next station will be accumulated to this value of (K). if the clock indicates a repetition of loop, assume the navigator will give instructions to the pilot to correct for drift and also that correction will be made for the camera swing. The program thus considers that the aircraft will fly to the next air-station as if the previous one was taken correctly on the required flight-line, with no camera swing. clock-C for forward overlap: if the clock does not indicate repetition of Loop-C, the new base will be the same as the previous base. Proceed with step (2.5). if the clock indicates need for forward overlap control: - survey the terrain along the flight direction for (1.5) base lengths (taking into account camera attitude of the previously located station). - calculate ground clearance (in reality sensed by apparent ground speed) for 6 points along flight line: 3 points at one base length and the other 3 points at 1.5 base length. This group of 3 points is : one point along flight Line, one point at 3/4 upper ground coverage and one point at 3/4 lower coverage of the previous photo. - take the miniumum ground clearance of these points and that of the previously located exposure station (this point of min. Clearance is in reality equivalent to the apparent fastest point in terrain) - calculate new base length which corresponds to this clearance in the following way: - try to locate a point along the flight direction (either actual one after loop-B or the shifted one by the drift value assigned to the previous exposure station). - clearance of this point is the minimum clearance and its component. W.R.T. flight Line is either 'zero' or the previous drift. value. - its corresponding photopoint is taken on the overlap edge of the previous photo. ^ from the information it is possible. to find. its ground coordinates and the corresponding base value, i.e. flying distance from position of the previous air station. This flying distance is the new base. - Check value of new base with previous one: if the difference is within threshold, take old base (this means that navigator does not recognise that relative ground speed is faster than the reference lines in the forward overlap regulator). - 175 -
