Oscilloquartz launches enhanced PRTC solution for 5G network timing
Oscilloquartz, an ADVA company, has launched its enhanced primary reference time clock (ePRTC) system to enable unprecedented timing accuracy and stability even when the GNSS signal is lost. The technology provides the ideal timing source for missioncritical transport systems, such as utility networks; government infrastructure and radio access networks, and provides the strict synchronization needed for LTE-A and 5G applications. Featuring the OSA 3230B ePRC atomic cesium clock connected to an Oscilloquartz clock combiner and grandmaster, the new solution offers the extremely stable frequency of a cesium clock with the UTC-traceable signal provided by GNSS. What’s more, when combined with the OSA 5430, the OSA ePRTC system is the only solution available that provides full hardware redundancy and multiple fan-out options including PTP over 10Gbit/s. www.oscilloquartz.com.
Broadgnss releases high precision GPS receiver
Broadgnss Technologies recently announced a new high precision satellite position receiver with patented RAC (Real-time Array Calibration) technology. It features positioning accuracy better than one meter (up to 10 centimeters). By receiving only single frequency (GPS L1) satellite signals, the RAC technology in high precision satellite positioning frees the dependence on traditional augmentation network and significantly reduces the cost to enable high precision satellite positioning to enter large-scale applications. RAC receivers are designed to balance the performance and cost, overcoming some common barriers of traditional high accuracy GNSS receivers.
H2H leveraging EGNSS for safer maritime navigation
Using EGNSS (EGNOS and Galileo), the Hull to Hull (H2H) project is developing a system that will allow maritime vessels to navigate safely in close proximity to each other and to stationary objects, supporting mariners as they take navigation decisions and creating the fundamental conditions for autonomous maritime navigation.
Funded by the European GNSS Agency (GSA) under Horizon 2020, the H2H system will combine sensor information with 3D models to create digital models of vessels and other objects of interest. This digital model can be visualized by the mariner in 3D, or in 2D format using slices of the 3D model, and used to derive crucial navigation information in real time. The quality of the sensors and the 3D model will drive the quality of the digital model, and consequently the quality of the navigation information that is derived from the model.
Mapbox’s new SDK helps developers build smart AR navigation apps
Mapbox, the open source mapping service that competes directly with Google’s Maps Platform, has announced a new software development kit (SDK) that will make it easier for developers to build applications that provide AR navigation. That by itself would be cool, but by using ARM’s Project Trillium AI platform, the Mapbox Vision SDK can also recognize other vehicles, pedestrians, speed limit signs, construction signs, crosswalks and more, all without having to train their own machine learning models to do so.
Using ARM’s Project Trillium platform, the SDK is able to make use of the mobile device’s onboard CPUs, GPUs and AI chips (if available) to perform the necessary object recognition. Once new phones launch with ARM’s new ML and object detection processors, the SDK will be able to perform all of these functions even faster, but for now, it can extract features from the video feed at a speed of about ten times a second.
Telit launches GNSS integrated antenna receiver modules
Telit, a global enabler of the internet of things (IoT), has debuted its SE878Kx-A series of GPS and GNSS integrated antenna receiver modules for consumer and business applications. As per the company, these modules require high performance, maximum reliability and low power consumption.
Moreover, the SE878K3-A and SE878K7-A are compatible with GPS, GLONASS, Beidou and Galileo and also enable device vendors to develop quickly and costeffectively location-based IoT solutions for use in virtually any country worldwide. The SE878Kx-A series supports dual internalexternal antennas to ensure connectivity when one is broken or compromised, along with a SAW filter to maximize jamming immunity. According to Telit, these features make the modules ideal for missioncritical applications and other use cases where reliability is key, such as alarms, stolen cars or high-end asset tracking.
Harris Corporation delivers fifth GPS III satellite navigation payload
Harris Corporation has provided Lockheed Martin (with its fifth of ten advanced navigation payloads contracted for the U.S. Air Force GPS III satellite program.
The GPS III navigation payload features a Mission Data Unit (MDU) with a unique 70-percent digital design that links atomic clocks, radiation-hardened computers and powerful transmitters – enabling signals three times more accurate than those on current GPS satellites. The payload also boosts satellite signal power, increases jamming resistance by eight times and helps extend the satellite’s lifespan. Lockheed Martin successfully integrated the navigation payload into the fifth GPS III space vehicle (GPS III SV05). Harris is committed to delivering three more payloads by the first quarter of calendar year 2019 for GPS III SVs 06-08.
Concept3D interactive map and virtual tour platform
Concept3D, a leader in creating immersive online experiences with 3D modeling, interactive maps and virtual tour software recently announced that The University of Maine in the USA is the latest major university to launch on the Concept3D platform. With the platform, richly detailed 3D models are built atop Concept3Ds interactive map system, making it easy and fun to explore the campus and surroundings from a mobile device on campus or anywhere in the world. The platform also enables the ability to offer 360-degree panorama images, giving map visitors the ability to feel as if they have jumped right into a specific campus location.
Mapping for the city of the future
The Land Survey Division within the Singapore Land Authority (SLA) develops mapping and positioning data and administers the cadastre and mapping framework for Singapore.
The purpose of mapping is to capture landscapes and streetscapes, digitize these data and make them available for other uses. In its first phase of mapping, an airborne laser scanning and imaging equipment was flown over Singapore to collect 3D point cloud and imagery data of the whole nation.
Phase two of the national 3D mapping project involved a comprehensive mobile mapping project that was carried out to collect a ground-based laser scanning and 360 panoramic imagery dataset on approximately 6,000 km of roads. The data collected was used to create 3D models of road and street furniture. These data sets would be used to create the first nation-wide 3D maps of Singapore, which will contribute to the development of a Smart Nation. The 3D digital models are taken into Virtual Singapore to be used by the public, private and people (3P) and research sectors.
UAVs for island management
In support of the Whole-of-Government push for a Future Ready Public Service, the Singapore Land Authority (SLA) has been actively driving innovation in land management regime. SLA recently conducted an Unmanned Aerial Vehicle (UAV) proof of concept (POC) at Pulau Seringat.
The objective of the POC was to establish whether fully-autonomous UAVs operating beyond visual line of sight (BVLOS) were effective for the inspection and automatic detection of maintenance issues on offshore islands managed by SLA. The offshore islands were identified as an ideal testbed for the POC as they provided a conducive environment to test the remote deployment of UAVs, as a pre-cursor to full-scale deployment on these islands.
Safran reveals Geonyx inertial navigation system for assured PNT
Safran has developed a new family of inertial navigation and pointing systems for land vehicles, called Geonyx. It provides alternative assured position, navigation, and timing (APNT) if GNSS such as GPS or Galileo are unavailable due to physical constraints, jamming, or spoofing. It can be used autonomously or in a hybrid configuration in conjunction with GNSS. The system is based on Safran’s Crystal hemispherical resonator gyro (HRG) that has been used in a range of applications in multiple domains for several years, such as in missile guidance and space navigation. The HRG measures the rotation of a platform to calculate its exact position and attitude. A stationary resonance wave is maintained electronically inside a silica hemisphere (a resonator).
This wave remains fixed in relation to an inertial reference, such as stars. By measuring the relative angle between the vibration plane and the resonator, the rotation of the platform can be calculated and its position and orientation deduced. ihs.com
