Raymarine E70310 Raystar RS150 GPS/GNSS Receiver — 72-Channel | SeaTalkNG | NMEA 2000

Raymarine E70310 Raystar RS150 GPS/GNSS Receiver

The Raymarine E70310 is the Raystar RS150, a high-performance 72-channel GPS/GNSS receiver designed as a dedicated external position sensor for Raymarine SeaTalkNG navigation systems. It delivers fast 10 Hz position updates — ten position fixes per second — with GPS, GLONASS, and SBAS augmentation for improved accuracy in all conditions. The RS150 connects directly to the vessel’s SeaTalkNG backbone and supplies position data to all compatible network devices simultaneously: chartplotters, autopilots, radar, AIS, and instruments.

The standalone E70310 includes the RS150 receiver, a 6 m SeaTalkNG spur cable, mounting hardware, and a sealing gasket. The pole-mount variant is listed separately as T70327; the optional pole-mount adapter for an E70310 installation is A80370, available separately.

Part Number Reference

• E70310 — Raystar RS150 standalone (this product)
• T70327 — Raystar RS150 with pole-mount kit included
• A80370 — RS150 pole-mount adapter (sold separately, compatible with E70310)
• A06072 — RS150 SeaTalkNG spur cable replacement / extension

Installation Notes

• Mount the RS150 where it has a clear, unobstructed view of the sky — avoid locations shadowed by radar domes, antennas, or superstructure
• Keep the receiver away from other high-power RF sources (VHF antennas, AIS antennas) by at least 0.5 m where possible
• Connect the included 6 m SeaTalkNG spur cable to any available T-piece on a powered SeaTalkNG backbone
• Seal the mounting surface with the included gasket — do not omit the gasket on horizontal surfaces exposed to standing water
• Verify the navigation display recognises the RS150 as a GNSS source in the network device list after installation
• For NMEA 2000 networks, connect via a SeaTalkNG to DeviceNet adapter cable (A06076)

Technical FAQ

• What is the difference between E70310 and T70327? E70310 is the standalone Raystar RS150 receiver with cable and surface-mount hardware. T70327 is the same receiver supplied with the pole-mount adapter kit. If you want pole mounting and don’t already own the A80370 adapter, T70327 is the more complete package; if you are surface mounting, E70310 is the correct choice.
• Why would I need an external GPS receiver if my Axiom MFD has built-in GPS? The RS150 provides a faster 10 Hz update rate compared to the internal GPS on most Raymarine MFDs (typically 1–5 Hz). This matters most for autopilot tracking accuracy and radar MARPA target plotting, both of which benefit from high-frequency position updates. It also provides a dedicated antenna location with an unobstructed sky view, improving reception in helm-enclosed or hard-top installations.
• Does the RS150 supply position data to all devices on the network? Yes. Once connected to the SeaTalkNG backbone, the RS150 broadcasts position, speed over ground, course over ground, and time data to all compatible devices on the network simultaneously — chartplotter, autopilot, radar, AIS, and instruments all receive the same GNSS source.
• Is a SeaTalkNG backbone required? The RS150 connects via a SeaTalkNG spur to a SeaTalkNG backbone. A backbone with at least one powered T-piece is required. For NMEA 2000 installations, the A06076 adapter cable bridges SeaTalkNG to a NMEA 2000 Micro-C network. If building a new backbone, see the A25062 SeaTalkNG Backbone Kit.
• What SBAS systems are supported? WAAS (North America), EGNOS (Europe), MSAS (Japan), and GAGAN (India) — providing wide-area differential GPS correction across all major coverage regions.

Parts Desk Insights

Best Use Case: The RS150 (E70310) is the right choice when adding a dedicated high-speed external GPS source to a Raymarine SeaTalkNG system — particularly for vessels with an autopilot that needs faster position updates for accurate track-keeping, or where the internal MFD GPS antenna is physically blocked by a hardtop, radar arch, or helm enclosure. The 10 Hz update rate makes a noticeable difference in autopilot steering smoothness and MARPA radar target tracking at speed.

Common Issues: The most common ordering mistake is confusing E70310 with T70327 — if you need pole mounting, T70327 includes the pole-mount hardware; E70310 does not. Surface mounting is the default with E70310, using the included gasket and hardware. A second common issue is sky-view placement: the RS150 must have an unobstructed view of the sky — mounting it under a radar dome, near a VHF antenna, or inside a helm enclosure will degrade reception. Plan the mounting location before ordering to ensure a clear overhead view from the installation point.
