    Tersus GNSS has updated its surveying smartphone app, Nuwa. The latest version includes features such as vector map import and digital surface stakeout.

    The Nuwa app runs on Android and is reliable, and easy to operate. It has rich and powerful functions that can help surveyors complete measurements more efficiently and accurately.

    The app is designed to work with the David and Oscar GNSS receivers from Tersus GNSS, plus other receivers that support NMEA-0183.

    New features in Nuwa version 2.3.3.2 include:

    • Vector map import and stake. The new version supports importing vector maps in DXF, LandXML, KML, and KMZ formats in the import module, optimizes the loading speed of vector maps for display in the Survey and Stakeout interface, and allows direct clicking to select points and lines on vector drawings for staking.
    • Digital surface stakeout. The new version supports importing DXF files containing 3dface entities and LandXML files containing surfaces, manually selecting points to form Delaunay TIN, and entering surface offsets for fill and cut value interpolation calculations in Surface Stakeout.
    • Update version description. Now, when receiving a version update, the highlights of the latest version are displayed directly in the application, including essential or market-focused features and fixes for issues.

    Existing features of Nuwa include:

    • Ability to configure base, rover and static surveys
    • Graphical interface with background map (online/import)
    • CAD stakeout, road stakeout and earthwork
    • Data management (import/export multiple formats)
    • Support for Bluetooth and USB connections
    • Various built-in tools.

    Empowered by a high-precision inertial measurement unit (IMU) on the Ultimate version, the Oscar from Tersus GNSS is a new generation of tilt survey receiver. Its calibration-free tilt compensation is immune to magnetic disturbances ­— holding the survey pole upright is no longer necessary. Powered by Tersus ExtremeRTK GNSS technology, Oscar can provide high accuracy and stable signal detection.

    The built-in high-performance antenna can speed the time to first fix (TTFF) and improves anti-jamming performance. With a Nano-SIM card, Oscar can access the internet and transmit and receive correction data through 4G/Wi-Fi. The built-in UHF radio module supports long-distance communication. A detachable smart battery can display power levels. Two batteries support up to 16 hours of fieldwork in 4G/3G/2G-network and rover-radio mode. Oscar can be configured through a 1.54-inch interactive screen on the Ultimate and Advanced versions. The IP67-rated rugged housing protects it from harsh environments.

    The Tersus Caster Service (TCS) helps surveyors set up a GNSS base station quickly to broadcast a correction stream via mobile networks. Natively supported by FieldGenius and Nuwa App, Oscar can be configured to different work modes to suit various daily jobs.

    Satellite Tracking. Oscar supports multi-constellation and multi-frequency satellite tracking, including GPS, GLONASS, BeiDou, Galileo, SBAS and QZSS.

    Accuracy. With enhanced positioning accuracy and constellation tracking, even in harsh environments, Oscar controls deviation within 3cm in surveying and mapping applications.

    Quick Fix. Oscar can fix integer ambiguity rapidly after tracking satellites and receiving correction data: 3–5 seconds in the open sky, and 10–30 seconds under canopy or near buildings.

    Tersus GNSS Inc. has launched Tersus Oscar, its new generation GNSS real-time kinematic (RTK) system.

    Oscar is an all-in-one GNSS receiver that can be used as rover or base system. Paired with a Tersus TC20 controller or A11 mobile terminal, Oscar can more efficiently meet customer application requirements for the optimal surveying solution, according to Xiaohua Wen, founder and CEO of Tersus GNSS.

    “Last year, we launched the David GNSS receiver,” Xiaohua said. “This year, we are very excited to introduce an advanced version of David; we named it Oscar.”

    Oscar supports calibration-free tilt compensation function, meaning a leveling pole is no longer required. Configuration is made easy with a 1.3-inch interactive screen. With an internal high-performance multi-constellation and multi-frequency GNSS board, the Oscar GNSS receiver can provide high accuracy and stable signal detection, the company said.

    The high-performance antenna can speed the time to first fix and improve anti-jamming performance. The built-in large capacity battery can support up to 10 hours of fieldwork.

    A radio module in the package supports long-distance communication. With its rugged housing material, Oscar is protected from harsh environments.
