April 1, 2025 Nothing beats the feeling of settling into your favorite fishing spot and enjoying the peacefulness of the water while you patiently wait for fish to bite. It’s a hobby for anglers of all experience levels and any age. So whether you fish for a sense of relaxation or for the thrill of the catch, it’s important to know what you’ve got on your line and where you are likely to get lucky […]

Unicore has introduced the UM981 series, a high-precision positioning module that integrates RTK and inertial navigation system (INS) technologies. The solution leverages GNSS and INS navigation to cater to applications in precision agriculture, surveying and mapping. The module is compatible with all major navigation systems and frequencies, tracking signals from multiple systems simultaneously for enhanced performance even in challenging environments. Additionally, the UM981 series supports open Precise Point Positioning (PPP) services such as BDS-3 PPP-B2b, […]

March 28, 2025 What is heart rate zone training? Should you wear a heart rate monitor? Your body works harder when you’re running instead of walking. When you sprint, your body may push to its limit. Ever wondered just how much more effort that sprint requires? Heart rate zone training may offer some answers. Whether you’re a beginner runner, a marathon regular or dedicated cyclist, knowing how to train with your heart rate zones can […]

Figure 2: PPP and PPP-AR technology evolution in terms of accuracy versus convergence time. Essence Since the dawn of GPS, researchers have worked to improve the accuracy of estimated positioning, navigation and timing (PNT) from the receiver-derived pseudorange, carrier-phase and Doppler measurements. While the pseudorange-based accuracy of standard point positioning (SPP) at the level of 1s to 10s of meters sufficed for most users, carrier-phase-based relative positioning, real-time kinematic (RTK), network RTK (NRTK) and precise […]

The following papers focus on high-accuracy positioning for autonomous vehicles in various environments. The papers are available here. High-accuracy and resilient GNSS receiver for autonomous vehicles The G3STAR GNSS receiver, a […]

March 24, 2025 What are the benefits of a Garmin product with solar charging, and how does it work? Let’s break it down. The battery life on Garmin smartwatches lasts a long time — we’re talking days and weeks instead of hours. With solar charging available as an additional benefit on select Garmin smartwatches (and other Garmin outdoor products), you may even be able to measure your battery life in months — or it may […]

SBG Systems has released the New Ellipse, a firmware upgrade for the Ellipse product line. The system can now be used as an attitude and heading reference system or inertial navigation system. Powered by the latest-generation sensor fusion algorithm, the New Ellipse is designed to enhance navigation, attitude, and heave performance for stable and accurate positioning even in high-dynamics environments and challenging conditions. Additionally, it introduces advanced GNSS-denied capabilities, featuring newly integrated flags that trigger when GNSS jamming or […]

Jammertest 2024. (Photo: David Jensen) For the fourth consecutive year, Jammertest will take place in Bleik on Andøya, Norway, with applications now open until March 15, 2025. This event serves as a critical platform for industry and equipment manufacturers to test their systems against jamming and spoofing attacks, identify vulnerabilities and develop more resilient solutions. It attracts participants from diverse sectors, including the global automotive and security industries, telecommunications, academia and government authorities. The event’s […]

Astranis has completed a critical demonstration for the U.S. Space Force’s Resilient GPS (R-GPS) program, showcasing its ability to transmit core GPS waveforms using software-defined radio hardware. Conducted ahead of schedule and within budget, the demonstration highlights Astranis’ ability to adapt its flight-heritage high-orbit satellite hardware to meet new resilience requirements for the Space Force. The test took place at Astranis’ headquarters in San Francisco, California, using a flight-like software-defined radio and positioning, navigation and […]
