  1. IGS M-GEX - The IGS Multi-GNSS Global Experiment • Aug 2011 - Call for Participation released • Oct 30, 2011 - Proposals due • Dec 15, 2011 – Proposals evaluated by the Organizing Committee • Feb 1, 2012 – Experiment begins • Jul 23-27 – First Results Evaluation and discussion at IGS 2012 Workshop, Olsztyn, Poland • August 2012 – Experiment ends for temporary installations; tracking continues for permanent installations • Note: Interested organizations can join at any time http://www.igs.org

  2. IGS Multi-GNSS Global Experiment • Call for tracking sites • - expansion of continuous tracking network according to • IGS standards • - include other stations (temporary or not IGS standards) • that can enable engineering analysis of Multi-GNSS • - antenna calibrations strongly encouraged/ required • - software receiver encouraged • - RINEX V3.01 format • Call for Data Centers • - archive tracking data and make it publicly available

  3. IGS Multi-GNSS Global Experiment 2012 • Call for Analysis - Analysis and engineering analysis strongly encouraged (at least notice plans) - not to disrupt the daily IGS operations and delivery of data and products ! • Call for collaboration with federated networks to realize multi-GNSS global network - JAXA Multi-GNSS Demonstration Campaign, Asia - CONGO network - CNES network - others

  4. IGS Multi-GNSS Global Experiment • Call asks in first place for timely RINEX tracking data - track as many signals as possible (focus on GNSS, but can include SBAS) • Analysis of the new multi-GNSS assumed as an element of IGS ACs on a ‘best effort’ basis • Analysis and engineering analysis by other interested groups strongly encouraged • Include Real Time tracking aspect and signal utilization which will be coordinated by the IGS Real-Time Pilot Project and WG

  5. Proposals (as of Dec 2011) • 3 Datacenter (CDDIS, IGN, BKG) + 1 RT Data Center (BKG) • several Analyses Proposals (IGS AC +3 other) • About 35 stations + 7 JAXA sites • 3 Trimble NETR8 + 10 Trimble NETR9 + 1 Trimble NETR5 ?? • 6 LEICA GRX1200+GNSS + 1 Leica GR25 + 1 Leica GR10 • 4 JAVAD TRE_G3T DELTA + 1 JAVAD TRE_G3T DELTA • 1 TPS NET-G3A • 1 NOV OEM6 • 1 SEPT POLARX4TR • 1 IFEN NX.NTR.500.D +1 IFEN SX.NSR.V2.801 (Software Receiver)

  6. Proposed M-GEX sites (as of April 2012)

  10. MGEX – BKG RT-Data Center (April 23,2012) About 15 data streams / predominately RTCM

  13. BKG MGEX Ntrip User Information /3 • Stream Upload to M-GEX Ntrip BroadcasterThose who answered the M-GEX Call for Participation with the intention to contribute with tracking data are kindly requested to upload their raw stream via Ntrip and the receiver firmware to the M-GEX Caster. Please contact igs-ip@bkg.bund.de to receive a mountpoint and an ID for that along with further stream upload details. • Stream Retrieval from M-GEX Ntrip BroadcasterThose who answered the M-GEX Call for Participation with the intention to process and analyse incoming data may like to apply for an account to retrieve streams in real-time from the M-GEX Caster. Authorization is provided through a Registration. Note that this concerns only streams made available in HP MSM format. Streams in proprietary raw vendor formats will not be disseminated. • The Open Source 'BKG Ntrip Client' (BNC) is able to decode observations encoded to HP MSM by the Stream Conversion Tool and may thus by an appropriate software for you. Further software which might be helpful in the M-GEX context is available from here. • Status: January 9, 2012

  14. Site Summary As of today • 25 sites provide observation data -- 25 daily files (24 RINEX V3.0x; 1 RINEX V2.11) -- 12 sites provide hourly files -- 6 high rate files (1s; from RT stream) * 16 among them (also) as RT streams Problems • Currently no JAXA data (seems to be resolved by end of April) • Currently no CONGO data • GSI data (3 stations mentioned to be late)

  15. Technical and administrative issues • Consistent PRN assignment of GIOVE and Beidou satellites • RINEX Format for QZSS (3.02) • RINEX and RTCM –MSM conversion of RT streams for some receiver types (JAXA) • Some email exchange but currently no software receiver data • New proposals avaialble at CB? • Lack of time (RW)

  16. We strongly encourage interested groups and especially manufacturers to support this experiment by proposing additionals sites equipped with their most recent multi-GNSS receivers (currently Novatel, Septentrio, Topcon , Ashtech not or under-represented) • Experiment can be joined any time • Jul 23-27 – First Results Evaluation and discussion at IGS 2012 Workshop, Olsztyn, Poland Thankyouforyourattention
