Satellites are visible below the horizon due to atmospheric refraction Warning Care must be taken when using ECUTOFF because the signals from lower elevation satellites are travelling through more atmosphere and are therefore degraded Use of satellites below 5 degrees is not recommended The Omnistar HP XP process is not affected by the ecutoff setting The elevation cutoff angle for HP XP is 8 degrees 1 A low elevation satellite is a satellite the receiver is tracking just generally anywhere between 0 and 15 degrees above the horizon Low elevation satellites are usually setting or rising There is no difference in the data transmitted from a low elevation satellite to that transmitted from a higher elevation satellite However differences in the signal path of a low elevation satellite make their use less desirable Low elevation satellite signals are noisier due to the increased amount of atmosphere they must travel through In addition signals from low elevation satellites don t fit the assumption that a GPS signal travels in air nearly the same as in a vacuum As such using low elevation satellites in the solution results in greater position inaccuracies The elevation cut off angle is specified with ECUTOFF to ensure that noisy low elevation satellite data below the cut off is not used in computing a position Experimenting with different cut off angles can be done to provide the best results In cases where there are not enoug
