GPS Challenges
Unintentional Interference Sources
- Very weak signals
- Receiver technology improving
- Satellites appear to be robust - solar storms, etc.
UWB - Ultra wide-band transmissions
- For now, car radar, motion detection, short-range communications
- But: later, a nationwide CDMA cell-replacement system
- Strong industry push; good political connections
- Loran-C is not affected by the current UWB designs
