Pharos, named for the Lighthouse of Alexandria, produced early handheld GPS navigators and navigation software (Traveler 505/525, Ostia, Smart Traffic) for PocketPC and Windows Mobile. These products helped bring turn-by-turn routing and traffic information to consumers, but the market has since moved to iOS/Android apps and integrated car systems.
Automotive GPS uses satellite signals (and often multiple GNSS constellations) to provide meter-level positioning, real-time routing, traffic updates, and telematics for drivers and fleets. Modern systems combine on-board sensors and connected data for more reliable guidance.
A modernized look at the Garmin GPSMAP 376c: a mid-2000s handheld/chartplotter that combined land and marine navigation, satellite weather, and multimedia playback. Useful historically and for basic offline navigation, but now a discontinued legacy device compared with current chartplotters and smartphone apps.
A practical guide to directional and omnidirectional external Wi-Fi antennas, placement, installation tips, and when to use them with modern Wi-Fi equipment.
How to compare and test broadband performance using modern tools (Speedtest, iperf3, traceroute), what metrics matter (latency, throughput, jitter, packet loss), and a practical troubleshooting checklist.
GPS vehicle tracking has moved beyond alarms to connected telematics that enable live tracking, stolen-vehicle recovery, geofencing, crash alerts, and remote services. Choose a system by balancing features, connectivity, installation, ongoing fees, and privacy.
A look back at the Garmin GPSMAP 376c: a 2006 handheld color chartplotter with satellite weather and optional sonar, and how modern chartplotters have evolved.
The Garmin c340 was a mid-2000s automotive GPS known for on-screen maps, voice directions and route recalculation. Today it remains useful as an offline navigator, but live traffic and current maps are better handled by modern devices or smartphone apps.
A modern overview of how auto GPS works: satellites, trilateration, device roles, accuracy improvements, and what GPS can and cannot do.
The Garmin StreetPilot c340 was prized for its simple touchscreen, reliable routing, and flexible mounting. Today it's a capable legacy GPS for offline navigation, but modern smartphones and current Garmin models offer more live features and map updates.
GPS watches combine satellite positioning and onboard sensors to record routes, monitor heart rate and calories, provide navigation, sync to apps, and offer safety features like incident detection and SOS.
