2 Overview Session 2: Waste Tracking via GNSS Current State-of-the-Art Tracking & Tracing Chaz Dixon, Telespazio VEGA Operational Concepts of Tracking Waste Viney Dhiri, Telespazio VEGA Operational Deployment Experience of Waste Tracking Brendan Mallen, IP Forensics (Ireland) Ltd In this talk: Devices In-vehicle Covert Systems Performance Limitations

3 Devices (1): In-vehicle Specific Product (or a Service) dedicated to Waste Management Client Receives Tracking Reports Real time (or not) info relayed to vehicle fleet management office Improve accountability & Vehicle routing / re-routing & Fuel efficiencies / driving style monitoring Geofence Notifications Notification if vehicle leaves a zone or deviates from a route Can also be theft protection Notification if a vehicle enters a forbidden zone Example providers of tracking service GPS Insight : Position Logic : Trackimo : trackimo.com/ Track your Truck : Image: Dieselboss.com Point + radius or Zone Image: locationsmart.com Image: Gofleet.com

4 Example Track from Vehicle Dots (Records) every (e.g.) 5 minutes (1-15 minutes typical for tracking) Typically sent to HQ in near real-time Image: DieselBoss.com

5 Devices (2): Covert Miniature device (optional support service) to track a target covertly Widespread use in other sectors; Few examples of using GNSS tracking to track waste 2 Main Categories GNSS Chip added to existing electronics package Size: 4mm 2 (e.g. Sony ) Power: 10mW (e.g. Sony) operation, μw standby. Tracker Module typically includes GNSS, Comms, microprocessor, Memory, Battery Size: 64 x 46 x 17 mm Weight: 50g Power: 800mAh Li-ion battery (80 hours continuous operation*)

6 80 hours continuous operation* Smart processing Increase interval between position measurements (off in between) Miniaturised accelerometers detect motion (Unit is off / standby until motion detected) Calculate position, but only report if moved Calculate position & store (relay batch of data) Calculate (or report) only on interrogation May extend continuous operation to 1 year or more without recharge New concerns: the environment (esp. temperature), comms network access, was something missed between reports?, Coming one day Energy harvesting (Motion, solar, RF, ) Specific to environment Generally not yet useful

7 How the Systems Work Tracking Centre GPS, Galileo, Glonass, Beidou GNSS Signals GSM, GPRS (or other Comms) Internet Comms Network Client Access HQ &/or remote Tracked Vehicle, etc.

8 Performance Coverage: Global, 24 x 7 continuous Availability: Effectively 100% (see coverage) but with identified limitations Accuracy: ~2m (H1σ) for ordinary user equipment, (including very low SWaP equipment) ~10 m (H1σ) for covert trackers. Accuracy worse due to generally poor antenna siting in covert mounts. E.g. could be beneath a vehicle or in a wheel arch. ~1m (H1σ) for ordinary SBAS user equipment. ~few cm achievable with specialist equipment; (no perceived need for waste and vehicle tracking applications?) Reliability: Very reliable. Local checking (RAIM) can be implemented in receivers to confirm integrity where required (e.g. Safety-of-Life). GNSS position and time records are used evidentially in UK and other Courts (Where did he go? When? How fast? Did he rendezvous with?) Image: Garmin

9 Limitations Normal GNSS limitations: Worse performance or unavailable indoors Unavailable underground & under water Normal Comms limitations: No connectivity in some places (esp. {but not only} remote) Different connectivity (GSM / CDMA, Different network) Normal System limitations Battery power limits life of self-powered units Abnormal GNSS / Comms limitations RF Interference Spoofing / Faked positions or position records Tracker can becomes detached from target
