Differential GPS Spare Parts Suppliers

Differential GPS (DGPS) gives ships position accuracy down to one meter or better, against the 5–10 meter spread of standard GPS. It works by receiving correction signals from shore-based reference stations through MF radio beacons or satellite links. DGPS is required on most commercial vessels for navigation, ECDIS feeds, and dynamic positioning. When a unit fails, the bridge loses one of its main position references, and the AIS, ECDIS, and autopilot may all be affected. 

RecordsMarine maintains a directory of differential GPS spare parts suppliers for navigation officers, ETOs, and purchasing teams, keeping their bridge electronics in good order.

Common DGPS Spare Parts

A DGPS installation has several replaceable elements:

  • GPS antennas and antenna cables
  • MF beacon antennas
  • Receiver units and processor cards
  • Display heads and control panels
  • Power supply boards and fuses
  • Junction boxes and signal splitters
  • Mounting brackets and weatherproof housings
  • NMEA cables and serial converters

Each item carries its own type approval, especially on units linked to GMDSS or DP systems. Approved suppliers of spare parts for differential GPS keep certified replacements in stock for the most common installed brands.

Critical Items to Stock Onboard

A few items are often kept in technical stores to avoid voyage delays:

  • Spare GPS and beacon antennas
  • Backup processor card or receiver unit
  • Antenna cables in standard lengths
  • Power supply fuses and circuit boards
  • NMEA junction modules

Most failures trace to antenna cable damage, water ingress at connectors, or aging power boards. Working with proven providers of spare parts for differential GPS shortens lead times when the vessel is calling at a remote port and the bridge needs the unit back online quickly.

Recommended Brands

The DGPS market is led by a small group of established makers:

  1. Furuno
  2. JRC (Japan Radio Company)
  3. Trimble
  4. Hemisphere GPS
  5. Saab TransponderTech
  6. Koden
  7. Simrad
  8. Garmin Marine

Spares matched to the original maker stay traceable during navigation surveys. Recognized distributors of spare parts for differential GPS supply OEM and class-approved aftermarket parts with proper paperwork.

What to Check Before Ordering

Useful points to confirm before placing an order:

  • Type approval matching your flag state requirements
  • Compatibility with the installed receiver model
  • NMEA 0183 or NMEA 2000 protocol support
  • Antenna gain and frequency band match
  • Stock visibility for legacy units still in service
  • Delivery time to your next port call

A quick phone confirmation with the technical superintendent before ordering avoids costly mismatches.

Industry Standards

DGPS equipment must meet SOLAS Chapter V Regulation 19, IMO Resolution MSC.112(73), IEC 61108-2 for DGPS performance, and ITU radio regulations on beacon reception. Type approval is mandatory on commercial vessels, and spare parts for safety-critical components must carry the same certification as the original installation.

Frequently Asked Questions

How long do DGPS antennas last? 

Most run for 8 to 12 years before signal degradation calls for replacement.

Can I use generic GPS antennas? 

No. DGPS receivers need certified antennas matching the original gain and pattern.

What is the lead time on a replacement unit? 

Common items ship in 1 to 5 days. Legacy parts for older receivers can take 2 to 4 weeks.

Are older DGPS receivers still supported? 

Many brands still hold stock for units that left production a decade ago. Check the model number first.

Do I need a technician for installation? 

Antenna swaps usually need a qualified ETO or radio engineer. Cable changes can often be done by a trained crew.
