New GPS Performance Document Gives Glimpses of L2C, L5, Expanded Constellation

The U.S. Air Force updated the GPS Standard Positioning System (SPS) Performance Standard (PS) in mid-April, 2020, the first new Performance Standard document since 2008. It includes mention of and pre-Initial Operating Capability (IOC) performance standards for the new civil GPS signals L2C and L5 for the first time. In another new feature, the document mentions “expanded capabilities which allow the total size of operational constellation to grow beyond the previous maximum of 32 Navstar satellites” for “more robust constellation availability to enhance the overall SPS SIS performance.”

Testing for Sure: Safety in Autonomy, a Two-Day Learning Experience

In three hours over two days, this special virtual workshop and professional learning experience rigorously investigates safety, integrity, standards and testing for precise positioning in automotive, both driven and driverless. It asks — and answers! — these crucial questions:

MIMO-GNSS Signal Processing for Precise Indoor Timing

Future telecom, finance and energy sector applications may require time synchronization of tens or hundreds of nanoseconds. A joint time and composite MIMO channel estimation method for indoor receivers can meet these stringent requirements.

Green Lane Speeds Border Crossings of Essential Goods

Galileo Green Lane, a new mobile app, facilitates the free movement of freight, reduces waiting times at European Union borders, and prioritizes essential goods during pandemic response. The app uses Galileo positioning services to address the needs of border control authorities and truck drivers, with two intuitive user interfaces. The app was developed by the European GNSS Agency (GSA) in collaboration with the European Commission.

5-cm Accuracy in Marine-Certified Receiver: Quad-Band Device Supports PPP Corrections

A new marine-certified quad-band GNSS receiver, the LD900 from VERIPOS, delivers accurate, reliable positioning in demanding offshore environments. The LD900 can track four GNSS frequencies simultaneously to ensure a precise position is always available at sea. When combined with Apex5 correction services from VERIPOS, it delivers accuracy levels as precise as 5 cm (95%) to provide robust positioning for the most challenging applications, including deepwater drilling, seismic, construction, and survey.

The New Flex Power Mode: From GPS IIR-M and IIF Satellites with Extended Coverage Area

GPS satellites usually transmit their signals with constant power. However, a so-called “Flex Power” is foreseen to increase the strength of individual signals to better fulfill operational constraints. Flex power operations can be detected in carrier-to-noise density ratio (C/N0) observations provided by GNSS receivers of the global tracking network of the International GNSS Service (IGS).

Securing GNSS – A Trip Down Cryptography Lane

We trace back through time to witness the progress in anti-spoofing solutions and describe how we arrived at the designs being implemented today; principally GPS’ CHIMERA, Galileo’s OSNMA, and ICAO’s SBAS data scheme.

Positioning, Navigation, and Timing Trust Inference Engine

Critical infrastructure has a compelling need to infer the assurance of PVT estimates—as do users in general. However, traditional PNT platforms do not offer a principled way to infer assurance from multiple anti-spoofing (A-S) techniques, situational awareness (SA) information, and other auxiliary sources such as network data. Here we introduce, a PNT Trust Inference Engine (PNTTING) that can assess PNT trust according to probabilistic models with rigorous semantics.
