CWA 16874:2015

The purpose of this document is to define a technical specification and the test suite in order to perform evaluation processes to guarantee that a product can be labelled as “EGNOS Enabled”.
The main goal of the EGNOS labelling scheme is to assess that user equipment uses EGNOS in their location and timing services. Therefore, the essential requirement for a product is to compute the EIPVT (EGNOS Improved Position Velocity Time).
The scope of the document is EGNOS capable products for mass market applications using EGNOS Open Service and/or EDAS. In the context of this CWA, mass market users are understood as non-safety/non-liability critical and non-professional users. The considered products are chipsets, terminals and applications.
