Simplifies product development for high-precision applications

The TFM.110A is the first in a new series of high-precision, multi-band GNSS front ends for autonomous vehicles, precision agriculture, automotive applications and robotics. It comes fully integrated with two cascaded low noise amplifiers (LNA) and pre-filters in a small, low-profile, shielded surface-mount package. When used between the device’s GNSS receiver and antenna, the two-stage amplifier solution eliminates the need for complex and challenging onboard filter and amplifier circuits. It supports L1, L2 and L5 bands and enables seamless signal transmission, signal purity and position accuracy in high-precision applications.

Provides interference, spoofing, encryption and authentication capability

Version 2.8 of the NCS Nova RF signal simulator offers advanced capabilities. With integrated interference generation capability, the Nova can generate coherent interference signals with a signal power of up to –30 dBm. The ability to assign two users to one RF output enables integrated spoofing scenarios with a single RF output, meaning spoofing is available even with an entry-level single RF Nova. The new release has advanced navigation message authentication simulation capability compliant to User ICD 1.0 for the Galileo E1-B OSNMA, meaning specific OSNMA events can be simulated — key to ensuring compliant receiver behavior. Supported events include renewal and revocation of both a public key and a TESLA keychain. GPS cross-authentication and generation of Galileo E6-C encrypted codes are also supported.

Enables first responders to locate callers on floor levels

Z-axis location service enables the pinpointing of a smartphone user within one floor level inside a multi-story building. The technology — demonstrated to meet the 3-meter vertical location accuracy requirement of the Federal Communications Commission (FCC) — is integrated into Schok Gear’s newly released flip phones. The Schok phones provide consumers with a simple, powerful device. Adding indoor and vertical location to these phones enables first responders to locate all wireless 911 callers with floor-level accuracy in multi-story buildings.

Connected with free mobile app

The new ACR Electronics GlobalFix V5 Emergency Position-Indicating Radio Beacon (EPIRB) and ResQLink AIS Personal Locator Beacon (PLB) have integrated the automatic identification system (AIS) to increase the speed of location and aid. They also are compatible with Return Link Service (RLS) alerting. The combination of services ensures faster rescue and increases chance of survival of both boat (EPIRB) and crew (PLB). The safety beacons deliver mobile connectivity to a cell phone with a free mobile app, made possible with the addition of near-field communication technology in the beacons. With the app, users can monitor their beacons, review self-test results, view GNSS test locations, and monitor beacon performance and maintenance by scanning the beacons with their mobile phones. Besides GNSS positioning, the lightweight beacons have 406-MHz Cospas-Sarsat distress signal with MEOSAR compatibility and 121.5-MHz local homing signal.

For Internet of Things deployments

The Canvas Device Manager simplifies workflows for configuration and maintenance of internet of things (IoT) device deployments. It enables users to easily set up devices, monitor performance, and keep software up-to-date across the entire IoT device fleet. Device parameters can be remotely managed, and performance monitored. Canvas enables users to organize large numbers of devices to quickly build and maintain IoT solutions, and software updates can be remotely and rapidly deployed, thwarting security attacks.

Advanced technologies in a slim, portable unit

The N2 Palm RTK GNSS receiver is suitable for surveying, mapping and construction. It has a highly integrated main board and a three-in-one antenna, yet weighs 0.72 kg with battery and measures 48 mm. Powered by ComNav’s SinoGNSS K8 high-precision module, the N2 can track 1,590 channels, including all existing and planned signals of GPS, BDS-2, BDS-3, GLONASS, Galileo, QZSS and SBAS. Its advanced satellite-tracking technology ensures it works well even in harsh environments, such as under heavy foliage or close to buildings. A third-generation inertial measurement unit (IMU) makes the N2 immune to magnetic disturbance, which greatly improves its reliability. Pole-tilt compensation of up to 60° allows surveyors to locate points within 2.5 cm. By using the company’s Quantum algorithm, the N2 achieves calibration-free operation — after 10 seconds of initialization, users can make tilt measurements with centimeter-level accuracy for an extended period, greatly improving efficiency.
