1 European officials consider licensing Galileo to mobile devices

 

The European Commission is beginning to realize that the European GNSS will be available in the third or fourth, following GPS, GLONASS, and possibly even Beidou, so the EU is exploring non-market strategies to increase the use of Galileo's manufacturers or users.

 

 

2 Spirent launches global satellite navigation system, multi-zone \SBAS simulator

 

(Launches All-GNSS, Multi-Regional/SBAS Simulator, SBAS is a regional wide-area differential augmentation system built using geostationary satellites)

 

Spirent has introduced a new generation of multi-frequency, multi-GNSS RF constellation simulator - GSS9000. The GSS9000 supports a wide range of constellation configurations and includes classified or restricted signals. Multiple antenna and multi-vehicle configurations are available, such as differential global navigation satellite systems, attitude determination, interference/interference and spoofing, and controlled receive mode antenna (CRPA) testing.

 

 

3 New GLONASS-M satellite starts commissioning

 

The GLONASS satellite launched last week has begun the commissioning phase in the slot 18 of the Russian Global Navigation Satellite Constellation Track 3, which lost three spacecraft in the crash of a Proton rocket since last July. GLONASS has been successfully launched for the first time. Telemetry communication is established after the GLONASS-M spacecraft (designated GLONASS No. 754) reaches orbit.

 

GLONASS currently has 24 operational satellite transmit signals and three on-orbit spares.

 

 

4 Trimble's UX5 UAV System Captures Images

 

Trimble's UX5 UAV System is an aerial imaging and mapping tool for precision agriculture, surface mining and construction. The UX5 captures aerial imagery for a wide range of applications, measurement, crop and livestock management. It combines a GPS receiver, radio photogrammetry, remote sensor, a lithium-ion battery, plus an electric motor to propel itself. The UX5 is stable at 80 km/h (50 miles) with significant crosswinds and even light rain. Equipped with a camera modified to capture near-infrared spectroscopy, it helps to infer the health assessment of vegetation crops.

 

 

5 Quanzhou: The development of the Beidou mobile phone and railway navigation system

 

Quanzhou City, Fujian Province actively grasped the application market of Beidou positioning and railway navigation, and developed the Beidou positioning mobile phone and railway navigation and positioning system. This newly developed Beidou positioning mobile phone is equipped with Beidou navigation chip in the machine. In addition to the ordinary navigation function, in case of emergency, the user can send SOS distress signal to the Beidou positioning center, and the mobile phone automatically transmits the user location information. If there is no area covered by the mobile phone signal, the user can also send text messages to the ordinary mobile phone through Beidou satellite. This function can achieve nationwide coverage without blind spots. According to reports, the current mobile phone is still in its infancy. Before mass production and market entry, there are still some problems in terms of volume, power consumption and cost.

 

6 NovAtel Introduces OEM 617D Single Card GNSS Receiver with RTK

 

NovAtel has released the OEM617D receiver, a compact, dual-antenna, dual-band, single-card receiver with NovAtel's ALIGN heading functionality and RT in both dynamic and static environments. - 2 real-time dynamic (RTK) GNSS positioning technology.

 

The OEM617D offers GPS, GLONASS, and Beidou signals for full dual-band operation to maximize the availability of GNSS. It also tracks Galileo, SBAS and QZSS. Designed for rotary wing aircraft, ships, autonomous ground vehicles, and applications requiring precise position and heading accuracy.

 

 

7 FlexPak-S GNSS enclosure provides defensive spoofing module positioning

 

Novatel has introduced the flexpak-s GNSS expansion enclosure, which includes a NovAtel dual-band OEM625S receiver card that integrates the L-3 XFACTOR Select Availability Anti-Spoofing Module (SAASM).

 

When licensed as an integrated defense module, FlexPak-S provides centimeter-level real-time dynamic (RTK) location services by taking raw measurements from XFACTOR SAASM and applying them to NovAtel's advanced RTK algorithms.

 

In Standard Positioning Service (SPS) backup mode, FlexPak-S continues to provide centimeter-level accuracy with NovAtel's dual-band civilian GNSS positioning engine. The FLEXPAK-S' backup mode is configurable for GPS or GPS + GLONASS mode.

 

The FlexPak-S was developed for a size-constrained environment, so it's small and lightweight. Although it is small, its casing has been carefully designed to ensure reliability even in harsh environments. The degree of protection is IP67, the housing is waterproof and has a wide operating temperature range. The FlexPak-S uses a standardized hardware connection and a complete set of NovAtel software for easy integration. The SAASM location is specified through a dedicated communication port, as well as the NovAtel software protocol, for maximum flexibility. The FLEXPAK-S is designed in the same form factor for the FlexPak6.

 

 

8 The second IRNSS satellite arrives at the orbital position

 

The Indian Space Research Organization (ISRO) reported that the second tilted geosynchronous orbit (IGSO) satellite in the Indian Regional Navigation Satellite System (IRNSS) has reached its intended orbital position and is operating normally.

 

The satellite navigation system currently built in India is different from the configuration of other global satellite navigation systems. India’s demand for satellite navigation systems is regional, so current investments are only used to develop regional systems consisting of seven satellites. In general, navigation satellites are positioned in the mid-earth orbit. However, the four satellites in the Indian regional navigation satellite system will be located in the tilted geosynchronous orbit (the IRNSS-1A satellite and the IRNSS-1B satellite are already in this orbit), and the remaining three will be located in geosynchronous orbit.

 

 

9 Trimble Announces Integrated Multi-Constellation GNSS, RTK Application UHF Module

 

Trimble has introduced a new BD930-UHF receiver and communication module that combines a tri-band GPS/GLONASS/Beidou/Galileo receiver with an integrated ultra high frequency (UHF) module.

 

As part of Trimble's global navigation satellite system OEM portfolio, the new compact module features centimeter-level, real-time dynamic (RTK) positioning. By integrating wireless communication into the same module, the BD930-UHF module is greatly simplified.

 

Ethernet connectivity and on-board Web server allow for high-speed data transfer and configuration via standard browsers, while the module also supports USB and RS232 interfaces.

 

The BD930-UHF offers the latest in global navigation satellite systems and communication technology in an easy-to-integrate form factor that meets demanding conditions and application requirements such as field calculations, port automation and lightweight robots or drones.
