A system and method for position determination using low earth orbit satellites. A mobile terminal affixed to an asset initiates a collection of global positioning system satellite measurements (e.g., code phase) based on a hardware trigger generated by a low earth orbit satellite modem. Timing information reflective of the time of the hardware trigger pulse is transmitted to an operations center along with the global positioning system satellite measurements to enable the operations center to determine a position of the mobile terminal.
