GARMIN GPS 15L & GPS 15H

The GPS 15L and GPS 15H are more fully featured board level products that add WAAS capabilities, on-board voltage regulation, fully programmable NMEA 0183 sentence selection, programmable baud rate and true RS-232 drivers to the features offered by the GPS 15.

GPS 15H and GPS 15L sensors are designed for a variety of OEM system applications, including car navigation, wireless communications, marine navigation, mapping, and more. When receiving locally valid WAAS corrections, the GPS 15L and GPS 15H can provide position accuracy to less than 3 meters, 95% typical, without the use of an external DGPS beacon receiver.

GPS 15H and GPS 15L also offer excellent EMI/RFI performance for easy integration into systems that will be operated near mobile computing devices and wireless communications equipment. These are complete GPS systems that require minimal additional components to be supplied by an OEM or system integrator. A minimum system must provide the GPS with a source of power, a GPS antenna, and a clear view of the GPS satellites. An active antenna is recommended for improved performance. The system may communicate with the GPS 15H and 15L via 2 RS-232 compatible receive channels, and one transmit channel.

Available in high and low-voltage configurations (8-40 V unregulated and 3.3-5 V ± 100mV ripple), the GPS 15H-F and GPS 15L-F utilize an eight-pin LIF connector and can be adapted to your individual application. Both offer one-pulse-per-second timing for precise timing measurements.

For prototyping use, the GPS 15L-W and GPS 15H-W (with a different connector type on the board) comes with mating connector with pigtailed bare wire ends. This model is in limited supply; quantity orders are subject to a lead time of up to 6 - 8 weeks. For production use, the -F versions are recommended since there is much less labor in installing a flex cable than there is in doing point-to-point wiring. The flex cable will also produce a more geometrically repeatable connection to the board than loose wires, reducing the associated variabilities from unit to unit.

The GPS 15H and GPS 15L weigh approximately 15 grams, measuring about the size of a matchbook (1.400" wide x 1.805" long x 0.327" tall). Functionally, the GPS 15L and GPS 15H are like half-sized GPS 25's with WAAS capabilities. They are also significantly less expensive than their GPS 25 counterparts.

ACCESSORIES
• The GPS 15L and GPS 15H can use the GA27C antenna (recommended for prototyping purposes, but you may find smaller or less expensive antennas elsewhere.) The key requirements for the antenna are:
1) MCX male cable termination
2) Between 10 dB and 30 dB of electrical gain
3) Must operate properly from the 3.3 V bias applied to the center conductor of the MCX connector, relative to GND on the outer conduction (3.0 V for the GPS 15L versions)
• GARMIN 8-pin flex cable and connectors are now available (see below)
