Gemtek 4-8470-10 Tracking Device
Introduction
The Dagger-QG is a self-contained tracking device that combines the GPS with LTE and BLE connectivity. The Dagger-QG is a single endpoint device to a user or a server application. It canbe quired, updated and configured either through a serial connection, or an over the air LTE IP- network. The Dagger-QG prescents itself over these connections as an enhanced cellular modem with attached functional elements.
These elements include:
- GPS location engine
- General Purpose I/O (GPIO) pins
- Serial UART port
- Voltage monitor
- BLES.0
Application scene:
Hardware Design
Basic Hardware
The Dagger-QG provides support for specialized hardware features through AT commands. The features supported include the following.
GPS
The major functionality of the GPS system is to compute the correlation
results between the incoming signal and the selected PRN code based on certain
Carrier Doppler Frequency, Code Doppler Frequency, code phase, carrier phase,
and the particular satellite the system is tracking or acquiring.
GPIO
The GPIO pins are presented to the external environment on the main connector.
They are general purpose bidirectional lines capable of providing system
interrupts to generate a report or drive logic levels to external devices.
LEDs
Two LED status indicators are provided to verify correct installation (Red)
and operation (Green).
USER MANUAL
UART
A UART port is provided for AT command and data interaction and optionally for
application specific control.
Battery Monitor
The battery monitor is internal analog input scaled such that the DC valuc of
the power input pin to the Dagger-QG system is measured.
Watchdog
Qualcomm chipset supports internal software and hardware Watchdog.
Motion Detect
This function will work with firmware power down options to keep the Dagger-QG
in a very low power down state until motion is detected. Upon wakening, a
report can then be generated.

Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radiocommunications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio
ortelevision reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one of
the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
- This device may not cause harmful interference, and
- this device must accept any interference received, including interference that may cause undesired operation.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.
IMPORTANT NOTE :
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 20 cm between the radiator and your body. This transmitter
must not be co-located or operating in conjunction with any other antenna or
transmitter.
