1 Status & evolutions of Telemetry Services for Profiling Floats Brice Robert Patrick Bradley (CLS America)

2 COMPANY PROFILE CLS is a subsidiary of the French Space Agency (CNES), and was created in üunique operator of the Argos system üiridium services provider dedicated to ocean. & meteo. platforms With 2 global coverage LEO satellite systems and 3 processing centers operational 24/7, CLS is the privileged partner of ocean in-situ programs

3 CLS HEADQUARTERS CLS Headquarters in Toulouse, France.

4 CLS GROUP CLS Headquarters are located in Toulouse, France. Key facts about CLS Group: ü An international network of 20+ offices and subsidiaries ü 650 employees across the globe ü ISO 9001 certified

5 CLS ACTIVITIES

6 CLS ACTIVITIES

7 24/7 OPERATIONALITY Receiving, processing, monitoring, distributing and archiving data from satellites CLS Systems are MONITORED 24/7

8 CLS-TRACKED PLATFORMS OVERVIEW MAP Currently, more than platforms are tracked by CLS Science Platforms Fishing Vessels Ships

9 OCEAN SCIENCE PLATFORMS TRACKED AT CLS Ocean Platforms Met. / Ocean Moored Buoys Gliders Ice Buoys Profiling Floats Drifting Buoys Research Vessels

10 OUR MISSION Some of our Partners ücls provides satellite solutions to the scientific community for their ocean in-situ measurements. ü We help institutions and users to implement ocean observing systems Data collection Satellite equipment Positioning Data distribution Operational monitoring Data processing

11 CLS INVOLEMENT WITH ARGO CLS is involved at different levels with ARGO : ü DAC (GTS Processing for China & Korea) ü Validation of ARGO DATA with ALTIMETRY ütelemetry services provider

12 CLS & ARGO : HISTORY REVIEW From the start of the program, CLS has been a major partner of ARGO. For 10 years : ARGOS = close to 100 % of deployments ARGOS IRIDIUM

13 CLS & ARGO : CURRENT SITUATION 1813 ARGOS & 2168 IRIDIUM operational floats

14 CLS IS NOT JUST ABOUT ARGOS! METEOROLOGICAL OCEANOGRAPHIC CLS provides Iridium services for a lot of different applications : since 2007! Drifting buoys Moored buoys Land Stations Ice beacons Gliders Profiling floats (ARGO) Weather balloons AUV & USV Moored stations

15 CLS & ARGO : CURRENT SITUATION At CLS : 1813 ARGOS & 718 IRIDIUM (out of 2168) over 2500 floats at CLS = 2/3 of all ARGO floats

16 CLS IRIDIUM SERVICES FOR ARGO FLOATS Iridium SBD, RUDICS and CSD services are provided for ARGO floats.

17 FOR ALL CLS IRIDIUM USERS : MY DATA > PORTAL Online data consumption : for all services (SBD, RUDIC, CSD, etc.)

18 CLS DEDICATED SERVICE FOR ARGO Hosting service for RUDICS FLOATS allows all users to easily and securely manage their communication with their ARGO floats, via separate FTP accounts. CLS hosting is based on servers that are operational and monitored 24/7. Iridium satellites Internet RUDICS Floats Gateway FTP USER

19 CLS DEDICATED SERVICE FOR ARGO The key advantages of the hosting solution are: ü No need to open a RUDICS account ü 100% compatible with all main float type ü No need to maintain a connected server 24/7 (software & hardware upgrades, internet connection, etc.) üno need to develop a communication interface to manage data communication üauto-archiving of all data files ümaximum safety : server monitored and backed-up 24/7; 4 independent internet providers at CLS üquick activation of the service ü CSD / PSTN line for backup data calls ü Easy access to data through FTP / SFTP accounts

20 CLS DEDICATED SERVICE FOR ARGO Phase 1 : MAJOR UPGRADE IN 2016 Complete redesign of our hosting solution to make it : ümore stable & secured ümore efficient : no more delays ü Compatible with all types of floats ü More flexible (interfacing with user s softwares) Phase 2 : CONTINUED UPGRADE IN 2017 ütransfer of CLSA hosting with CLS : done same level of operationality ühosting of BGC floats (NKE) now fully operational, with compatibility with LOV interface ü Increased robustness of data : SFTP is now default, and passwords are CLS generated üupgrade of backup modem solution : switch to M2M ümore flexible pricing (accounting for non-transmitting periods)

21 STRONG COLLABORATION WITH FLOATS MANUFACTURERS CLS provides modems, SIM cards and all necessary hardware for both ARGOS and Iridium transmissions, and collaborate closely with main manufacturers regarding : ü The Integration of satellite transmissions hardware ü Floats testing prior to delivery ü testing of CLS hosting services, to ensure 100% compatibility USERS MANUFACTURERS

22 UPDATE ON IRIDIUM The FUTURE : Iridium Next ü $3 B Project for 81 satellites: 66 operational, 6 in-orbit spares, 9 ground spares, ü The new constellation will completely replaces the current constellation ü More bandwidth and higher speeds : up to 1.5 Mbps (vs bps) = increase of x 625! ü Service continuity & backwards compatibility ü Expected operationality : end 2018 / beg ü Iridium s goal a smooth transition to Iridium NEXT with incremental one-for-one replacement of satellites

23 UPDATE ON ARGOS ü Pricing : new ARGOS pricing currently being reviewed by OPSCOM ü New ARGOS 3/4 chipset available for integration (6 x 6 mm) more power efficient ü ARGOS-4 : 4 full-a4 payloads will be launched (to be confirmed) : OceanSat-3 (2019), CDARS ( ), MetOp-SG1b (2022), MetOp-SG2b (2029). Argos 4 = better link & power budget, larger messages (up to 625 Bytes per message), higher data rate (up to 4800 bits/s )

24 UPDATE ON ARGOS In parallel, a new ARGOS constellation is currently being designed by CNES : ü Nanosatellites, that should be deployed in 4-5 years ü constellation of 15 to 20 satellites

25 ARGOS ü ARGOS is evolving : new constellation being designed, A4 soon ready ü Only alternative to Iridium : global near real-time Low power, small transmitters No need to point the antenna to a satellite Data processing & delivery services ü ARGOS is a non-commercial system (as opposed to Iridium) ü ARGOS is not affiliated to any goverment (as opposed to Iridium) ü ARGOS community may want to keep a proportion on ARGOS in case of iridum failure? ü ARGOS still is a robust system, providing positionning (not dependant on GPS)

26 ARGOS AS BACKUP ON EXPENSIVE FLOATS? THE EXAMPLE OF GLIDERS Main Communication solution : Backup positionning solution : ü Near Real-Time ü Bi-directionnal ü Data collection & GPS ü Mission files uploading ü Remote configuration ü Autonomous tracking system ü ARGOS doppler Position (GPS free) ü Assisted Recovery with Goniometer

27 HOT TOPIC : BACKUP LINK ON FLOATS ü Only on Apex & Navis floats ü General rule : switch from RUDICS to CSD if 5 failed attempts to reach the RUDICS server. ü Was relavant when RUDICS could only handle one call at a time, but now there can be thousands of calls at the same time, and if a server is properly maintained and monitored, if should be up and running 24/7. ü So the only time the switch would happen is : ü During testing of floats ü 5 failed call attempts due to bad weatherà switching to CSD would not change the problem ü So what is the purpose of keeping the backup option? ü Maintaining analog phone line is more and more challenging (obsolete technology) ü One solution : modem to modem calls
