The DAQNAV system is a turnkey product for geophysical survey operators looking to carry out survey operations efficiently and accurately. The system combines 3D navigation, data acquisition and aeromagnetic compensation on a standalone Linux tablet PC.EVERYTHING YOU NEED TO BEGIN SURVEYING IN A SINGLE UNIT!
The DAQNAV system provides accurate 3D navigation to both pilot and operator to ensure precise survey flying. A Cross-Track bar indicates X,Y deviation from flight path, an Altimeter bar indicates ground clearance and a Terrain Display indicates Z deviation from a pre-planned drape surface.
The DAQNAV system records digital data received via USB, Serial, Ethernet or WiFi interfaces. Many devices such as GPS instruments, magnetometers and spectrometers provide digital output in this format. Other devices such as fluxgate magnetometers, altimeters and VLF often provide a simple output voltage that is first converted to digital using supplementary A/D converters. The DAQNAV system provides the user with a Diagnostic Window to monitor these various inputs. The operator can toggle between the Diagnostic and Map windows without affecting the surrounding Navigation information.
Aeromagnetic compensation coefficients for up to 4 magnetometers are calculated using software provided as a Geosoft GX. These coefficients can be used for aeromagnetic compensation of multiple magnetometers in real-time using the DAQNAV system or post-flight.
The compact design of the DAQNAV system makes it easy to install in all survey aircraft. The entire system runs on a 7" Linux tablet PC - installed in a variety of configurations using standard RAM mounting hardware.
The DAQNAV system was designed to interface with all of the latest geophysical equipment. DAQNAV configuration and installation is easily carried out to suit your project needs. The DAQNAV-I module comes with your choice of a 7" or 10" Linux Tablet PC and 3D Navigation enabled. As your your needs evolve to require Data Acquisition and Aeromagnetic Compensation you can simply upgrade your existing DAQNAV system to a DAQNAV-II or DAQNAV-III module. Upgrades are software based and can be done remotely.
To the right is an illustration of a sample DAQNAV system hardware configuration for all 3 DAQNAV modules.
Required 3rd party hardware to get started with 3D navigation is a GPS receiver. After that additional hardware can be added and DAQNAV module updates can be made as required.
