New eXtended Filtering (XF) is now employed in the TW3900 series of Accuntena precision antennas. The XF feature mitigates interference from all near-band signals and ensures the antenna provides the purest possible GNSS signals. The custom XF filtering has been tested to mitigate new (in Europe and Japan) and existing LTE signals, enabling the XF antennas to produce clean and pure GNSS radio frequency data. The XF models are TW3972XF, TW3972EXF, TW3972LGXF, TW3967XF and TW3967LGXF. All are triple-band antennas that support GPS/QZSS (L1/L2/L5), GLONASS (G1/G2/G3), Galileo (E1/E5ab), BeiDou (B1/B2/B2a), NavIC L5 and L-band correction services.

Cycling computer

Provides 72 hours of continuous tracking


The iGS320 cycling computer builds on the u-blox M10 positioning platform, leveraging the M10’s ultra-low power consumption, compact size, and ability to track all four GNSS to offer endurance athletes a superior user experience. Adopting the M10 in its iGS320 cycling computer brought iGPSPORT an 80 percent increase in the power autonomy to deliver 72 hours of continuous tracking, up from 40 hours in their previous device. Concurrent reception of up to four GNSS constellations increases coverage and accuracy in otherwise challenging signal environments.

The Triumph-3 receiver tracks efficiently even in difficult conditions. It can track all current signals and is ready for future satellites. The Triumph-3 can operate as a base together with Triumph-LS and Triumph-LS Plus to efficiently accomplish any geodetic job. Its RTK system communicates via integrated UHF, 4G/LTE, Wi-Fi and Bluetooth channels, and eliminates the need to subscribe to a real-time network for corrections. A powerful and reliable receiver for high-precision navigation systems, the Triumph-3 is based on the Javad GNSS 874-channel chip. It is equipped with an internal 4G/LTE/3G card and secure and accessible microSD and microSIM cards. It also supports Javad’s lift-and-tilt technology.

Eos Bridge enables almost any instrument to become iOS Bluetooth compatible. The pocket-sized device connects to instruments via Bluetooth Classic or serial port, and then transmits data to any Apple iOS device, such as iPhone or iPad, Android device or Windows mobile device. Instruments equipped with non-iOS Bluetooth can connect to Apple iOS devices using the Eos Bridge, including laser rangefinders and utility-locating instruments. Instruments whose only connectivity option is a serial port also can connect, such as any instrument or sensor with an RS-232 serial port. The Eos Bridge is lightweight, at approximately 150 grams (about 5.3 ounces). It can be worn clipped to a belt, stored in a pocket, or mounted to an instrument or sensor. The battery lasts 48 to 72 hours.

The OceanReports web tool provides users with specialized “ocean neighborhood analyses,” including maps and graphics, by analyzing more than 100 ocean datasets instantaneously. Reporting data includes information about habitats and species, industries in the area, potential hazards (such as undersea cables or shipwrecks), the economic value of ocean commerce, and other detailed oceanographic information. The web-based interactive tool for ocean mapping and planning, created by the National Oceanic and Atmospheric Administration (NOAA) and the Department of the Interior’s Bureau of Ocean Energy Management, provides professional users and the general public with opportunities to explore the ocean from their own computer.

Distress beacon

Indicates position in emergencies

Photo: ACR Electronics

The ACR 2830 GlobalFix V4 EPIRB marine distress beacon has multiple built-in redundancies to increase chances of survival in an emergency situation. The internal GPS receiver pinpoints the user’s location, which is then transmitted on the 406-MHz distress signal. In the absence of GPS-derived coordinates, the signal can be used to triangulate the position. The beacon’s 121.5 MHz homing signal will bring local search-and-rescue forces directly to the position; an LED strobe light allows them to see the position in low light. A Category 1 Emergency Position Indicating Radio Beacon (EPIRB), the GlobalFix V4 is a float-free device that will automatically activate when submerged in water. Two self-tests monitor transmission, power and battery performance as well as GPS acquisition.
