Spectra FOCUS 35 in Night time Topographic Survey

When a topographic survey for the main runway of the East Midlands International Airport was performed during nighttime closure, the Spectra Precision FOCUS 35 robotic total station turned in a stellar performance. Through cold November windy and rainy nights, with no task lighting permitted, the FOCUS 35 total station performed efficiently and flawlessly tracking the prism to 200 meters and beyond to help keep the project on time.

The runway topographic survey of 4,000 points was taken at 7.5m intervals longitudinally and at set locations across the tarmac. The set locations were predefined and uploaded as AutoCAD DXF onto the field controllers prior to commencing the survey. The positions were then located onsite and surveyed in the map screen to ensure the correct location was surveyed.

Poland Chooses MobileMapper 300

The agency responsible for the supervision and control of European Union agricultural subsidies in Poland, the Agency for Restructuring and Modernization of Agriculture (ARMA), has purchased 118 Spectra Precision MobileMapper 300 smart antennas. GPS/GLONASS/ SBAS L1/L2 receiver specifically is designed to be combined with a variety of mobile devices, including smart phones and tablets, running any thirdparty GIS application. ARMA is charged with verifying, through onthe- spot measurement of planted areas during the growing season, that the size of the declared cultivation and cultivated plant species are in line with the request for EU subsidies. The farms are selected for spot checks either randomly or through risk analysis.

The MobileMapper 300 was selected by ARMA because it enabled the agency to choose their preferred tablet solution, the Getac V110, and interface with their existing QGIS-based GIS application.

VN-360 GPS-Compass by VectorNav

VectorNav Technologies has introduced the VN-360 GPS-Compass heading and position sensor. It is an OEM GPSCompass module that provides an accurate, True North heading solution for systems integrators seeking a reliable alternative to magnetic-based sensors.

Many systems currently available on the market depend on digital magnetometers for providing heading measurements of a manned or unmanned platform. However, the majority of these platforms (e.g. multirotor UAVs, ground robots or satellite antennas) also include ferrous materials, motors, batteries or electrical components that drastically limit the ability of a magnetometer to provide an accurate or reliable heading solution. VectorNav’s VN-360 provides a miniature, cost-effective GPS-based alternative that is unaffected by these magnetic disturbances and changes to the magnetic environment. Incorporating two onboard GNSS receivers, the VN- 360 calculates the relative position between its two GNSS antennas to derive a heading solution that is an order of magnitude more accurate than a magnetic compass.
