1] denote the true azimuth angle and the true elevation angle of the first incident signal, respectively.
Error (e) was defined as the difference between the true azimuth ([theta]), determined using a hand held GPS unit, and the estimated azimuth ([theta]) of the transmitter for each azimuth i and replicate j as:
As shown in Fig 1, the measured angle forms a right spherical triangle with the true azimuth and the elevation.
Error arcs were derived by calculating the average deviation from the true azimuth in field trials of personnel asked to locate transmitters placed at various positions in the habitat (Hurst, 1997).
In most systems, the processor also accepts information about the orientation of the baseline (relative to true north or true local horizontal) to determine the true azimuth or elevation angle to the emitter.
