GPS
receivers are now a mature technology finding hundreds of applications
in location and timing, with the removal of the ‘dither’
(selective availability) signal, we now enjoy dramatically improved
accuracy and performance.
TDC Engineers have been involved in GPS since its commercial availability
in 1991, you will find that our experience and knowledge is second
to none.
The products in this section of the catalogue include chipsets,
OEM boards and packaged GPS Systems for System Integrators. |

Albatros
GPS Receiver
The Albatros OEM GPS Receiver from SENA GPS is a
new OEM GPS receiver product that features the SiRFstarII chipset.
Industry Leading GPS Performance
Signal acquisition using 1920 time/frequency search channels
Satellite signal tracking engine to perform GPS acquisition and
tracking functions without CPU intervention
Multipath-mitigation hardware
Cold Start in under 45 seconds
Advanced TricklePower mode for power savings to 98%. The TricklePower
mode allows to maintain the 1-sec update rate, yet the
chipset enters a sleep mode for almost 90% of each 1-sec
cycle
Extreme low power in power down mode, but capable of very fast starts
The unique feature of this module is it supports the functions of
the GPS receiver embedded applications written in JAVA language.
I/O lines and serial ports are then available for the OEM application.
An Evaluation and Development Kit for the Albatros system integration
and OEM developers is available to assess receiver performance,
begin development and fully incorporate Albatros into your application.
It includes antenna, cables and everything you need to integrate
the receiver, including Windows based Evaluation software. Use the
kit with confidence to prove Albatros's power and productivity in
all of your GPS mobile application needs.

Amigo-A
GPS Modem
The Amigo-A
contains a GSM modem and a high-performance GPS receiver in a
single case. It provides all the functionality of a modem, and
also allows you to obtain your GPS position by means of an extended
series of AT commands. At the same time, it facilitates the reporting
of your GPS position using GSM communication, while also adding
the functionality of a positioning device so that it can be controlled
from a remote base.
The unit contains a state-of-the-art GPS Albatros module designed
by Sena GPS. This module increases the system's power by offering
a series of commands specific to a GPS receiver: position, satellites,
channels...
The Amigo-W modem features the following functionality:
Operation in GSM telephone modem mode with the typical functions.
Reading and monitoring of GPS data via the control port on the
GSM modem, using an enhanced set of
AT commands.
Operation as a GPS positioning device, transmitting the data to
a Management Centre using the GSM modem. For this reason, it is
necessary to activate the phone number and authorised
access code on the GPS modem.
The Amigo-W is capable of reporting your position using three
different
mechanisms:
POLLING, in response to a position query. In case a position query
is received, it will answer using the format requested.
TRACKING CYCLE. You can set a cycle in order to have the positioning
device send your position voluntarily without being
requested.
EVENT ALARMS. When the following set events occur, the positioning
device will spontaneously send your position and
the reason for the notification:
Alarm
Triggers
- You exit an area set as an operation circle
- You reach the maximum authorised time away from your
base
- An alarm is triggered by the discrete input signal
