  • Page 26: Bias In Tec Measurements

    Operation 2.7.3 Bias in TEC Measurements NovAtel recommends calibrating the TEC to remove biases from TEC measurements. Sources of TEC measurement bias include the GNSS antenna, antenna cable, amplifiers, splitters, connectors, working temperature and equipment aging. TEC measurement bias must be determined during the time of day when the Ionosphere shows the lowest amount of activity.

    All oscillators have some inherent drift. By default, the receiver will steer its clock to accurately match GPS time. The GPStation-6 receiver automatically locks to the 10 MHz reference signal generated by the OCXO internal to the enclosure. Therefore, when clock adjustments are enabled the receiver will steer the OCXO towards GPS time.
