Overview
Garmin has as wide array of GPS products.  At this time I offer only the simple GPS receiver below.  The Garmin GPS 35-HVS was popular with SN10 owners because it was small and ran on 12V power.  However, it is no longer available.  The GPS 16-HVS is a very good substitute.  It is much less expensive and is a WAAS compatible receiver.  It also runs on 12V.  The only downside to the GPS 16-HVS is that it is a bit larger than the GPS35.

GPS16x-HVS Garmin GPS 16x HVS

The GPS 16x HVS sensor features a high-sensitivity receiver, integrated antenna and rugged, waterproof design that makes it useful for a variety of applications.

Get Accurate Data
This high-sensitivity, 12-channel receiver continuously tracks satellites and reports your precise position. It is also WAAS-enabled, so it can determine your precise location to within 3 meters — without using an external DGPS beacon receiver.

Leave Interference Behind
The GPS 16x HVS offers excellent EMI/RFI performance, so you can use it near mobile computing devices and wireless communications equipment without worrying about interference.

The GPS 16x HVS is a high-sensitivity GPS sensor that replaces the GPS 16.

This is a great, simple GPS for soaring applications.  I like it because it can be powered with 12 VDC and does not have a magnet built into it (like many small GPS units do).  It is WAAS compatible.

It is perfect for use with an LXNAV S7 variometer.  The S7 powers the unit with 12V and the GPS allows the S7 to do simply "get home" navigation with final glide calculations.

It works very nicely with the ILEC SN-10b because the SN-10b can power the GPS16x HVS.  When ordered with an SN-10b you can have the GPS16x HVS connected to the SN10's panel cable for $59.  A quick-disconnect connector is used to make it easy to route the GPS cable through small openings.

The GPS 16x HVS comes with a cable with an RJ45 (Ethernet) connector.  It can be ordered with an optional DB-9f connector for use with a Pocket PC.  The DB-9f connector plugs directly into a Goddard PS-5a power converter.  The PS-5a provides 12V power for the GPS16x and 5V power for the Pocket PC.

Note: The GPS 16x HVS defaults to a baud rate of 4800.  I can re-program it for any other baud rate for free.  I have PC cables setup for that.  I recommend 19200 baud if you think you may replace it in the future with a FLARM device.

Connector Options

  • RJ45 connector, the customer must connect the +12 VDC power, common and transmit lines. (standard)
    Note: It is necessary to connect 3 wires to common - The black (common), yellow (enable) and the shield drain wire should all be connected to ground.  That makes it tough to simply attach an RJ connector because it's not possible to stuff 3 wires into one slot on an RJ connector.
  • LXNAV S7 or S8 or S80 Variometer
    The GPS 16x-HVS works great with the LXNAV S7 or S8 of S80 variometer.  An RJ-Coupler-RJ45-RJ45 ($15) and Goddard Cable-GPS16xHVS-S7-0p3 ($50) can be used to connect the GPS directly to an LXNAV S7.  The S7 powers the GPS with 12V.
  • Let me know if you want me to shorten the power/data cable ($20).  It is supplied with a 5 m (about 16 feet) long cable.
  • Goddard PS-5a
    DB-9f, a standard connector for use with a Goddard PS-5a power converter and a Pocket PC. $30
    • PS-5a Pin 2 (GPS TX) to white wire in Garmin GPS 16x-HVS cable
    • PS-5a Pin 5 (ground) to black and yellow wires in Garmin GPS 16x-HVS cable
    • PS-5a Pin 7 (+12V) to red wire in Garmin GPS 16x-HVS cable
  • ILEC SN-10b panel cable-Customer Supplied, The customer's ILEC SN-10b panel cable is modified to connect the GPS 16x HVS to the SN-10b.  The SN-10b provides 12V power for the GPS. $59 for Modification
  • ILEC SN-10b panel cable-New, A new ILEC SN-10b panel cable is modified to connect the GPS 16x HVS to the SN-10b.  The SN-10b provides 12V power for the GPS. $59 for Modification + $63 for SN-10 Panel Cable = $122
  • SN10b-Pnl-PS5a-GPS16-x cable, This cable is used to connect the GPS16x HVS to both an SN-10b and a Pocket PC.  It replaces the SN-10 Panel Cable that comes with the SN-10. $119

Garmin-GA25-BNC Garmin GA 25 BNC GPS Antenna for Colibri, LX20, LX5000, LX7000 and LX7007 Products
Includes a 2.9 m (9.5 ft) cable with a BNC connector.  A similar antenna is included with the Colibri, LX7000 and LX7007.  It is not compatible with the LX8000.

Removable Magnets Installed
The antenna has 2 magnets installed under a thin metal plate on the bottom of the unit.  The magnets can be removed using a small screwdriver.  Just remove the clear plastic sticker that covers the back and set it aside.  Then remove the 4 screws at the outside corners.  It is not necessary to remove the 2 screws near the cable.  Then remove the metal plate and remove the 2 long flat magnets.  Then re-install the metal plate, 4 screws and clear plastic sticker.

I can shorten the cable to any length you desire.  I charge $19.95 for the new BNC connector and labor.  You can select the cable length when you place your order. There is also an option for a BNC-RA BNC elbow adapter for $9.95 (see below).  With the BNC elbow adapter the minimum recommended antenna cable length for mounting the antenna on top of a Colibri is 8 inches (20.3 cm).  Without the optional elbow adapter 10 inches (25.4 cm) is the minimum recommended antenna cable length for use with Colibri.

BNC-RA BNC Elbow
The BNC elbow can be used with some GPS and Radio antenna cables to reduce the amount of cable space required at the point the antenna connects to the device.  It is very nice for use on the bottom of the Colibri because it allows the use of a very short antenna cable.

GPS35 Garmin GPS35-HVS TracPak - No Longer Available
This is a great, simple GPS for soaring applications.  I like it because it can be powered with 12 VDC and does not have a magnet built into it (like many small GPS units do).  It is not WAAS compatible but the increase in accuracy available from WAAS compatible GPS units is not a big advantage for soaring pilots.

It works very nicely with the ILEC SN-10b because the SN-10b can power the GPS35.  When ordered with an SN-10b can have the GPS35 connected to the ILEC panel cable for $39.

The GPS35-HVS comes with a cable with bare leads.  It can be ordered with an optional DB-9f connector for use with a Pocket PC.  The DB-9f connector plugs directly into a Goddard PS-5a power converter.  The PS-5a provides 12V power for the GPS35 and 5V power for the Pocket PC.

Connector Options

  • No Connector, the customer must connect the +12 VDC power, common and transmit lines. (standard)
  • DB-9f, a standard connector for use with a Goddard PS-5a power converter and a Pocket PC. $19.95
  • ILEC SN-10b panel cable, The customer's ILEC SN-10b panel cable is modified to connect the GPS35 to the SN-10b.  The SN-10b provides 12V power for the GPS. (see photos below). $39
  • SN10b-Pnl-PS5a-GPS35-x cable, This cable is used to connect the GPS35-HVS to both an SN-10b and a Pocket PC.  It replaces the SN-10 Panel Cable that comes with the SN-10. $79

The Garmin® GPS 35 TracPak is a complete GPS receiver and embedded antenna designed for a broad spectrum of OEM (Original Equipment Manufacturers) system applications. Based on the proven technology found in other Garmin 12–channel GPS receivers, the GPS 35 will track up to twelve satellites at a time while providing one-second navigation updates and low power consumption. Its far-reaching capability meets the sensitivity requirements of land navigation as well as the dynamics requirements of high-performance aircraft.

The GPS 35 TracPak design utilizes the latest technology and high-level circuit integration to achieve superior performance while minimizing space and power requirements. Utilizing Garmin's own proprietary chipset, all critical components of the system including the RF/IF receiver hardware and the digital baseband are designed and manufactured by Garmin to ensure outstanding quality and capability.

The GPS 35 TracPak is housed in a black, water-resistant case and designed to withstand rugged operating conditions. While the GPS 35 TracPak is designed as a "plug 'n play" GPS solution, the minimum system must provide a source of power and a clear view of the GPS satellites. The system may communicate with the GPS 35 via two RS-232 compatible bi-directional communication channels. Internal memory backup allows the GPS 35 to retain critical data such as satellite orbital parameters, last position, date, and time.
