1	CORS/OPUS FUTURE PROSPECTS Delivery of some CORS data in near real-time via Ntrip OPUS-RS to process 15 minute data sets OPUS projects
2	Desired New Features Process multiple files as network Reduce occupation time to ~ 15 min Process single frequency (L1) data Publish OPUS results
3	Desired New Features Process multiple files as network Reduce occupation time to ~ 15 min Process single frequency (L1) data Publish OPUS results
4	STREAMING CORS DATA WITH NTRIP What format? What stations? What software? What distance? What data rate? What latency?
5
6	OPUS-RS Uses RSGPS program instead of PAGES (based on OSU MPGPS program) Uses P1 and P2 as well as L1 and L2 obs Resolves all ambiguities with LAMBDA Geometry free linear combination used to determine DD ionospheric delays
7	RSGPS
8	RSGPS May be used in two modes : Network and Rover In network mode, only reference stations are used and to solve for ambiguities and double difference ionospheric delays In rover mode, ionospheric delays and troposphere parameters are interpolated from reference stations to rover.
9	OPUS-RS Expected to produce solution with 15 minutes of data (vs. 2 hours for current OPUS) Network solution (rather than individual baselines) Expected accuracy approx. 2 cm horizontal and 4 cm vertical

11	OPUS-RS Interface will be almost identical to regular OPUS Output report will be similar to regular OPUS, but with quality indicators based on the W-ratio from the LAMBDA validation tests
