External Active GPS Antenna (Marine) with 2 Receiver Modules for Arduino Project

Up for sale here is a Marine grade external Active GPS Antenna with 2 Fastrax iTrax02/08 GPS receiver modules


The Antenna:

It has quite a strong magnet inside so will attach well to ferrous metals and also comes with an adhesive backed Velcro fastener.

The cable length is a nice 5m (approx 15 feet) which will allow you to mount this at some distance from the receiver.

It is rated at 2.4V to 5.0V max 15mA (This has to be supplied by the receiver, no external power source needed).

The connector is a Female FME type on RG-174 Cable, see     http://en.wikipedia.org/wiki/FME_connector

This would be great to replace a lost or broken one on a Boat / Van or Car.


This Bargain Package also includes 2 x Fastrax iTrax02/08 GPS Modules.

These 2 modules will be of use to someone that wants to experiment with GPS systems.

Technical Interface Description is here:      http://www.ko4bb.com/Manuals/05)_GPS_Timing/FastraX_ITrax02_en.pdf

A whole host of details can be found on the internet by searching for "itrax02"

Other components are required to get this working, ie a connector, a few capacitors, resistors.
See datasheet for details.

We have not yet done any development work with these so the only support available is via the internet.
We are intending to get a manual made up for these demonstrating how to use them shortly.


iTRAX02 Key Features:

• Tiny PCB form factor – 26mm x 26mm x 4.7mm (including RF shield and system connector).
• Ultra-low power consumption – 130mW @ 2.7V in continuous operation
• Very Fast TTFF
• Sensitivity –150dBm (Tracking)
• iTALK and NMEA0183 protocols
• Versatile interface ports
• Accurate 1PPS timing output
• iTRAX02/8 – 8MBit Flash Memory - iSUITE SDK Software Development Kit
• iTRAX02/4 – 4MBit Flash Memory - NMEA Engine

Fastrax’s iTrax02 GPS receiver modules enable the
implementation of full-fledged positioning features into any
appliance faster and with less effort than ever before.
Offering industry-leading benefits in performance, size, power
consumption and versatility, the iTrax02 receivers are ideally
suited for both industrial tracking systems and battery-operated
consumer products like mobile phones, asset tracking devices,
handheld computers and sports accessories.

Market Leading System Performance
Ultra-low, user configurable power management makes iTrax02 the
lowest power consuming, complete 12-channel GPS receivers on the
market. Nevertheless, there are no compromises in performance. The
iTrax02 receivers have a navigation sensitivity as low as –150 dBm
making them applicable even for extremely demanding applications
and environments.

Cutting component costs
Space and costs are reduced due to the cutting-edge technology
architecture in the iTrax02 receivers. All navigational data is stored in
Flash memory with simple commands and thus no back-up battery is
required. This benefit can easily be converted to smaller component
costs and smaller design – crucial parameters for many projects.

iTRAX02/8 – Versatile Programmability
The iTrax02/8 features 8MBit Flash memory allowing versatile
programmability with the iSuiteSDK (Software Development Kit).
Application costs are reduced significantly when no external processor
is needed and the iTrax02 is used as a microprocessor. With fewer
components, cost and application size are reduced.

Quick Start with Easy-To-Deploy Solution
The addition of an antenna and power supply is all that is needed to
make the iTRAX02 operational. The Fastrax support team can provide
antenna design application notes to aid in further refinement of the
antenna design for specific applications.
