CANE - Problem Problem: AFSCN utilization is at 81% daily. Current backup capabilities depend on specialized deployable systems and trained personnel to operate them. Required Capability: Quick reaction backup to AFSCN to off-load low priority / plain vanilla / conflict deleted SGLS contacts.
CANE- Solution Solution: Provide a commercially available service for conducting SGLS contacts Show dual USB / SGLS antenna capability Show augmentation of or surge capability to AFSCN Predicted Capability: Provide backup for AFSCN SGLS contacts Provide additional coverage for AFSCN (southern hemisphere, high latitude, LEO, site maintenance, surge activities) Another arrow in the 50 SW quiver
CANE- Timeline Timeline: Began collecting data - 15 Feb 01 Began BASIC CANE - 12 Mar 01 Began Advanced CANE - 17 Aug 01 Complete Demonstration - 17 Nov 01 Complete AIR - Feb 02
CANE- GOALS Demonstration Goals: Demonstrate SGLS TT&C Demonstrate SGLS ranging through commercial ranging box (RTLogic) Use DMSP, DSCS 2/3, and DSP TACO satellites Perform 876 contacts (846 SGLS + 30 USB) Examine quick turn-around between different SGLS satellites Demonstrate real-time network status using ITOS software (used by NASA) Use 56K modem & 128K ISDN for comm Examine use of internet for contacts Use USN AK site primarily Add USN Hawaii (HI) and Australia (AU) sites for downlink contacts

CANE - Successes CANE Significant Accomplishments: Telemetry Data Rates - 250 bps, 1k, 2k, 10k, 128k Commanding Data Rates - 1k, 2k Comm - 56k modem, 128k ISDN, Internet Quick turn-around times between different SGLS vehicles - consistently less than 10 min, some at 3-4 minutes Real-time Downlink Data Rate Swap between 2k and 10k Real-time Network Status Capability - ITOS
CANE - Preliminary Recommendations CANE proved it is feasible to perform simple SGLS TT&C using a commercial ground station Using commercial assets can offset infrastructure investment More work needs to be done: Continue with CANE Adjunct!Investigate commercial standards, protocols, and comm!investigate encryption options!successfully perform SGLS ranging!successfully conduct contacts from an operational SOC!Make recommendations for a Concept of Operations and Employment Concept
