A mobile device uses information from another mobile device to perform satellite position fix operations. The information enables the mobile device to perform the satellite position fix operation with less power. Additionally, the information enables the mobile device to determine a position of the mobile device more precisely at significantly lower power consumption. Example methods include receiving, via a wireless communication protocol, an indication of a space vehicle identification (SVID) and an indication of a frequency error for a space vehicle indicated by the SVID and performing an acquisition procedure for the space vehicle using the frequency error as a starting frequency. The method may further include receiving a ratio of the carrier power over the noise power for a unit bandwidth (C/N), determining an integration time based on the C/N, and performing the acquisition procedure for the space vehicle using the frequency errors as a starting frequency error and using the integration time.
