• Brand: Raymarine
• Model: Raystar RS150
• Official Product Type: GPS/GNSS Antenna with Pole Mount Kit
• System: SeaTalk NG / NMEA 2000

What This Product Does

The Raymarine T70327 is the Raystar RS150 high-performance GPS/GNSS receiver supplied together with a pole-mounting kit. The RS150 is a remotely mounted position sensor that connects to a Raymarine SeaTalk NG or NMEA 2000 network and delivers precise, fast-updating GPS position data to compatible chartplotters, autopilots, and navigation instruments.

Unlike an integrated GPS antenna built into a chartplotter, the RS150 can be positioned for the best possible sky view — useful on larger vessels or where the helm station has an obstructed view overhead. The pole mount allows installation on a standard rail or pole fitting.

Package Contents

• Raystar RS150 GNSS receiver puck

Compatible Applications

• Raymarine SeaTalk NG navigation networks requiring a remotely mounted GPS/GNSS position source
• Chartplotters, autopilots, and multifunction displays that accept external NMEA 2000 GPS input
• NMEA 2000 networks (requires a suitable DeviceNet adaptor cable — see Related Products below)
• Installations where the helm station or MFD has a restricted overhead sky view
• Vessels upgrading from an older or slower external GPS sensor to a 10 Hz GNSS receiver
• Rail or pole-mount installations using a standard 1” / 25 mm tube fitting

Mounting Options

• Pole/rail mount (this kit — T70327): Includes pole mount adapter for standard rail or pole fitting. Ideal for elevated, unobstructed mounting positions.
• Surface mount (standalone — T70310): Low-profile flush or surface mounting without the pole adapter. Choose this if you have a flat mounting surface with a clear sky view.
• Optional riser/clamshell kit (A80437) available separately — contact us for availability.

Parts Desk Insights

Best Use Case: The T70327 is the right choice when you need to mount the RS150 on a rail, arch, or pole to get it above obstructions — radar arches, T-tops, or sail rigs are typical locations. If you're replacing an older Raymarine GPS sensor that's losing satellite lock or providing slow updates to your autopilot or chartplotter, the RS150's 10 Hz rate and dual GPS/GLONASS reception is a significant upgrade. The included 6m cable covers most helm-to-arch runs without an extension.

Common Issues: If the unit isn't acquiring a position fix after installation, the most common cause is either a partial sky obstruction that's worse than expected, or the SeaTalk NG network not being properly powered and terminated. Confirm the backbone has terminators at both ends and 12V power applied before suspecting the antenna. Also verify the SeaTalk NG cable connections are fully seated and locked. For NMEA 2000 (non-Raymarine) networks, a DeviceNet adaptor cable is required — this is a separate purchase.

Service Interval

No scheduled service interval. Inspect the connector, cable jacket, and mounting hardware annually or when servicing adjacent equipment. Check the SeaTalk NG connector locking ring for corrosion or looseness. Replace the unit if GPS fix quality degrades significantly or position data becomes intermittent and network/cable issues have been ruled out.

Technical FAQ

• What is the difference between T70327 and T70310? Both contain the Raystar RS150 receiver. T70327 includes the pole mount adapter kit for rail or tube mounting; T70310 is the receiver only, intended for low-profile surface mounting.
• Can this be used with a non-Raymarine NMEA 2000 chartplotter? Yes — the RS150 is NMEA 2000 compatible. You will need a DeviceNet adaptor cable (such as the A06082) to connect the SeaTalk NG plug to a standard NMEA 2000 (DeviceNet) backbone.
• What does 10 Hz position update rate mean in practice? The RS150 sends a new position fix to the network 10 times per second. This provides smoother, more responsive position tracking on chartplotters and faster autopilot course corrections compared to older 1 Hz sensors.
• Does this unit include a cable? Yes — a 6 m (19.7 ft) SeaTalk NG cable is included in the T70327 kit. If a longer run is needed, SeaTalk NG extension cables are available separately.
• What waterproof rating does the RS150 carry? IPX6, which is protected against powerful water jets. It is suitable for exposed deck or arch mounting in normal marine conditions.
• Does it support WAAS? Yes — the RS150 is SBAS-enabled and supports WAAS (North America), EGNOS (Europe), MSAS (Japan), and GAGAN (India) correction signals.
