Positioning using a satellite requires defining the instantaneous positions of navigation satellites. The established positions are predicted and transmitted to the users applying satellites, and, however become degraded with accuracy in cases solar events divert the satellites from their path. Meanwhile, getting satellite coordinates with reference to the made predictions involves computing effort. The question addressed in this paper is whether orbit disturbances can be detected by examining these predictions so that computing coordinates are avoided. The paper argues that detection is possible but requires further experiments on confirmation due to the fact there have been relatively few solar storms in recent years while collecting data on satellite tracking. also, the paper also suggests that detection by examining orbital parameters is of a limited practical value when compared with the ease of interpreting satellite coordinates measured in meters.
