Yes.  Since this is a 3GPP performance test most of the stored information will have been received from the network as assistance data. 

The recs that I have in mind are 34.123 and 51.10 Section 70

Spelling is inconsistent ;)

This patch introduces support for Global Satellite Navigation System (GNSS),
using the AT commands AT+CPOS and +CPOSR as specified 3GPP 27.007.

+==========================================================
+
+Service		org.ofono
+Interface	org.ofono.AssistedSatelliteNavigation
+Object path	[variable prefix]/{modem0,modem1,...}
+
+Methods		void SendPositioningElement(string xml_element)
+
+			Send an XML element conforming to the XML DTD for <pos>
+			as defined in 3GPP 27.007 Table 8.55-2. This xml is
+			used for transferring data associated with positioning

In addition to these, I think there has been discussion of at least
having the fine time injection API, and in addition our positioning
guys would like to have a way of getting reference clock uncertainty
information from the modem. Of course, these can be added in separate
patches.

Overall, looks good to me.

Cheers,
Aki

Sorry to come back so late of this. By assistance data reset, you meant a reset of all positioning stored information? Like used in 3GPP conformance testing (44.014 § 8.15 for instance)?
The knowledge of positioning information is somehow "Assistance" information, but this is not the wording I'm used to.

Thanks,

Fred
