The leading pioneer in GPS technology Introduction

4 Who is NavCom Technology, Inc?  Located in Southern California  Major Business Areas - Proprietary Products for precise positioning & wireless communication - Product Services (Global Differential GNSS Corrections) - Contract Engineering  Acquired by Deere & Co. November Technology steward - NavCom remains “pathfinder brand”

The leading pioneer in GPS technology StarFire System Description

6 What is StarFire  Worldwide Satellite Based Augmentation System (SBAS)  Broadcasts satellite clock and orbit corrections  Utilizes six L-band satellites in geosynchronous orbits to provide duplicate global coverage 10 cm Positioning Anywhere, Anytime 10 cm Positioning Anywhere, Anytime

7 StarFire System User – Receivers and System Control - Processing Center Space – Signal Distribution Ground Tracking - Global Network

8 StarFire System - Ground Ground Tracking - Global Network

9 Reference Station Network Over 50 Reference Stations Worldwide  The network tracks all GPS satellites continuously – GNSS upgrades in progress  Survey grade receivers  Processing centers receive measurements from each reference station once a second

10 StarFire System - Control Control - Processing Center Ground Tracking - Global Network

11 StarFire Processing Centers  Two Processing Centers - Torrance, California - Moline, Illinois  Both Processing Centers Compute a Correction Stream for Satellites - Orbit Corrections once a minute (∆xyz ECEF) - Clock Corrections once every two seconds

12 StarFire System - Space Space – Signal Distribution Control - Processing Center Ground Tracking - Global Network

13 StarFire Uplink and Space Segment  StarFire channels on global beams of 6 different L-band communication satellites  All users see StarFire signals from two sources - Americas –Laurentides, Canada - Americas – Santa Paula, CA - Europe – Burum, Netherlands - Europe – Southbury, CT - Asia – Perth, Australia - Asia - Auckland, New Zealand Redundant Uplink Sites and Satellites

14 StarFire System - User User – Receivers and System Control - Processing Center Space – Signal Distribution Ground Tracking - Global Network

15 StarFire System Performance Reliability achieved by ensuring no single point of failure and thorough monitoring - Redundancy throughout entire system  From reference sites to broadcast signals - Extensive real-time monitoring  internal checks  real-time positioning results % availability  Under 6 minutes of outage annually

16 StarFire Integrated Receivers  StarFire SF Multi-frequency GNSS receiver - MEMs inertial attitude determination  StarFire SF-3050 Series - Military, Offshore, Machine Control markets - Full GNSS capability - CORS and Heading Functionality  StarFire SF Survey markets Worldwide decimeter accuracy in real-time

17Applications  Machine Guidance - Agriculture - Construction - Intermodal (port operations)  Offshore Survey  Aerial Survey  Autonomous Vehicles  Land Survey

The leading pioneer in GPS technology User Benefits

19 System Performance and User Benefits Real-time global accuracy - Less than 10 cm. one-sigma per horizontal axis (20 cm. vertical) - No local base station - Transparent communication link - Global availability

20 StarFire and Unaided Horizontal Accuracy 24 hour data sample

21  RTK Extend bridges the gaps in RTK coverage  RTK and StarFire operations all in ONE receiver  Patented innovation exclusive to NavCom RTK Extend RTK corrections No blockage. No problems. Blockage! Problems!!! StarFire corrections Continuous cm-level positioning for up to 15 mins.

22 RTK Extend Dynamic Test Results

23 Additional Benefits from StarFire Augmentation  Integrity monitoring - Broadcast correction stream contains validity flags for each satellite which are tightly monitored and controlled by the processing center software  Most common satellite vehicle error, clock runoff, detected early – PRN 02 example from 2006

24 PRN June 2006 (Indian Ocean) StarFire Provided corrections for 36 Seconds and then disabled the satellite StarFire Provided corrections for 36 Seconds and then disabled the satellite GPS System Invalid clock for 12 Minutes before setting the satellite unhealthy GPS System Invalid clock for 12 Minutes before setting the satellite unhealthy

25 PRN30 Effect on StarFire Positioning NCT-2100D Receiver Johannesburg, S.Africa No Effect on StarFire Positioning from PRN30 Clock Issue No Effect on StarFire Positioning from PRN30 Clock Issue

The leading pioneer in GPS technology Summary

27 StarFire Key Features and Discriminators  Only global SBAS owned and operated by a manufacturer of high precision GNSS receivers  Unique fusion of RTK with global SBAS  RTK-extend  Reliable, global decimeter accuracy in one receiver - Built-in StarFire capability - Independence from local base
