scope:
The present document defines Net Assist Protocol 2 that is optimized for TETRA air interface. It defines services:
• allowing information to be passed to a location determining entity;
• allowing a location determining entity to request assistance information.
The information passed to the location determining entity, when relevant, reflects the content and format of the equivalent information (navigation data) which passes from satellites to the location determining entity.
The protocol is capable of supporting more than one position determining technology. Presently it covers multiple GNSS, and is extensible to all network positioning methods.
