A seed inventory of CDGPS radios were built as part of the initial development of the CDGPS service that was launched in October 2003. Half of the inventory was distributed amongst the federal, provincial and territorial governments who underwrote the development of CDGPS, and the other half was designated for public retail through six resellers whose distribution networks covered the country.

The small size, rugged form-factor and low power draw made this unit ideal for portable applications. In addition, the onboard GPS chip enabled the receiver to output corrected positions in standard NMEA format for use with data recorder/PDA applications, eliminating the need for an external GPS receiver. The CDGPS receiver outputs corrections in localized RTCM SC-104, an industry standard format compatible with the vast majority of GPS receivers. The unit also outputs GPS*C, modified from the RTCA format, which is suitable for dual frequency GPS receivers.

The entire inventory of CDGPS radios was depleted by Spring 2005. There continues to be market interest but private manufacturers have not materialized to invest in replacement inventory to date.
