Unbranded Computer Accessories sku-14611960554 GPS

Unbranded sku-14611960554 is a Green module in the Computer Accessories category, made for indoor development use with the original USRP B210 and B200. It combines an OCXO and GPS receiver. The OCXO supplies a 10Mhz reference clock with 0.01PPM accuracy even without GPS reception, while the receiver supplies GPS messages. Pulse-based synchronization requires a GPS signal.

A typical GPSDO may drop to about 0.5PPM accuracy without GPS; this module maintains its 0.01PPM 10Mhz reference. It performs a GPSDO-like function but is not a true GPSDO.
