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. For safety. hazards such as towers and power lines can be added to a base map to provide advance warning to the pilots.
The DAQNAV system records digital data received via USB, Serial, Ethernet or WiFi interfaces. Most 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 compact Linux tablet PC that can be installed in all aircraft models in a wide variety of cockpit configurations using standard RAM mounting hardware.
The DAQNAV system design is robust and the 3 DAQNAV modules offered are designed to allow you the ability to easily scale survey operations as needed. To get started with just the essentials, the DAQNAV-I module comes with a choice of a 7" or 10" Linux Tablet PC and 3D Navigation enabled. As your your survey needs evolve to require Data Acquisition and Aeromagnetic Compensation capabilities you can simply upgrade your existing DAQNAV system to a DAQNAV-II or DAQNAV-III module. All upgrades are 100% software based and can easily 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.
Aircraft cockpits become cluttered during installation as Serial, USB and Ehternet cabling is used to transmit data from external geophysical instrumentation to the geophysical display and navigation system. These cabling assemblies also introduce potential weak-points in terms of reliable real-time data transmission. As cable length and quantity increases through the cockpit, so does the risk of data loss and corruption due to signal depreciation and physical wire damage.
The DAQNAV Wirefree module eliminates these risks and cleans up the cockpit by transmitting all incoming geophysical data to the DAQNAV system wirelessly. Installation is a simple process that requires the addition of the Wirefree hardware unit that accepts 120V/230V DC or 9-30V DC - common to almost all aircraft.
DAQNAV Wirefree is available as both an upgrade to existing DAQNAV systems or as an add-on to new purchases.
