  1. SiRFstarIV Receiver A2100-A/-B Business Unit Positioning Hans Wiedemann February 2010 Information is Vincotech Confidential & Proprietary. Do Not Reproduce or Distribute.

  2. Status 02/01/10 • First modules running in the lab • Further evaluation and tests in progress • Preliminary version of manual available • Flyer available shortly – technical specs still need some verification • Pricing available through your sales interface • Press release to be distributed shortly

  3. First Prototype Production

  4. Receiver Requirements • Shortest TTFF • Customers do not care about channels, correlators, Ephemeris (extended or not) – they want a fix NOW • Highest sensitivity • Fix under all conditions – no worries about an antenna • Lowest Power consumption • We mainly address telematics applications – but even here for asset tracking this is the second priority – certainly this is very often a combination with short TTFF • Jamming recognition, mitigation, removal • Especially automotive telematics suppliers ask for that – it is already normal in GSM products • Galileo support • Not a big issue today, but especially in Europe, customers are asking

  5. SiRFstarIV • -163 dBm tracking • -160 dBm navigation • -148 dBm acquisition (autonomous) • SiRFnav™ navigation accuracy • Tracks up to 8 jammers • Removes jammers prior to correlation • 10 power domains • 5 power states • 35 mW full power tracking • 8 mW trickle power @1Hz • 50-500uA continuous availability mode • Integrated temperature sensor • Smart Sensor support • Sensor interrupt support • Multi-master I2C bus • SiRFDRive support • SiRFDiRect support PRELIMINARY Addressing (nearly) all requirements!

  6. SiRFawareTM - Advantage SiRFaware™ Technology PRELIMINARY Auto- Cold Start TTFF • GPS OFF • Saves power, but… • Requires a lot of start-up energy • Compromises performance No Fix Aided Cold Start • GPS ON • Uncompromised performance, but… • Burns up battery power <100 <1s Trickle Power Tracking Energy [mAh] 0.5 50 500 5 It’s not off, it’s not on, it’s SiRFaware™

  7. SiRFawareTM - Basics PRELIMINARY • Q: What is SiRFawareTM good for? • A: SiRFawareTM keeps the module in a state of readiness for rapid navigation for long periods! • Q: When and how can I start using SiRFawareTM? • A: SiRFawareTM mode can be entered after an initial position calculation by software command! • Q: How is SiRFawareTM able to accomplish this? • A: SiRFawareTM will try to maintain position, time, frequency, and Ephemeris! • Q: Can I further improve SiRFawareTM? • A: SiRFawareTM can even be combined with Extended Ephemeris methods!

  8. SiRFawareTM – States Current [mA] 40 Data Collection Data Collection 30 Capture / Update Capture / Update Capture / Update Capture / Update Capture / Update Capture / Update 0.020 Time 1-10 mins 250 ms 18s 30 mins PRELIMINARY Typical current draw values

  9. SiRFawareTM – Power PRELIMINARY • Data Collection (re-load of Ephemeris) • Every 30 minutes for ~ 18s @ 40mA • Calc. average: 40mA x 18s / (30 x 60s) = 400µA • Targeted average: < 500µA • Results so far: ~ 300µA • Capture / Update (time, frequency, ... maintenance) • Every minute for ~ 250ms @ 30mA (worst case) • Calc. average: 30mA x 250ms x 30 / (30 x 60s) = 125µA • Targeted average: < 500µA • Results so far: < 300µA

  10. A2100 Overview PRELIMINARY Focus Application Main advantage Battery powered Highest Performance with passive antenna Typical handheld and demanding telematics applications; Portables, handhelds,fixed (often covered) vehicle and asset installations Superior SiRFstarIV features Wide A1084-B compatibility - 3.3V (A2100-A), foot print, pin out 1.8V option with A2100-B A and B prepared for sensor interfaces SiRFnavTM accuracy, highest sensitivity - Acquisition sensitivity -148 dBm (autonomous) - Navigation sensitivity -160 dBm - Tracking sensitivity -163 dBm SiRFawareTM technology / Extended Ephemeris Support

  13. Vcc should be always ON! Toggle ON_OFF from LOW to HIGH to wake up after power on…. Use software command to initiate and get back from SiRFawareTM and other low power modes… Necessary configuration for UART mode: Implementation PRELIMINARY Major difference towards A1084-B! Necessary to enable UART mode! ON_OFF pin must be connected! Necessary to wake up module – even after power off/on!

  14. Configuration via GPIO6 and GPIO7 pins Communication A2100-A PRELIMINARY Configuration Note: Host communication via I2C not possible due to level shifter in UART Tx path.
