CSR has announced the launch of SiRFstarV â„¢ 5e, an optimized Global Navigation Satellite System (GNSS) engine that enables high-precision positioning of mobile phones, cameras, and healthcare equipment. It can simultaneously support GLONASS, GPS, QZSS and SBAS, so it can ensure the highest positioning accuracy and the fastest time to first positioning (TTFF).
Telit CommunicaTIons plc is a professional enterprise of wireless solutions. The company will adopt SiRFstarV â„¢ 5e solution on its Jupiter SE868-V2 module. The Jupiter SE868-V2 module was first released by Telit Corporation at the 2013 American Wireless Communications Exhibition in Las Vegas, with a size of 11x11 square millimeters. This receiver module in QFN package integrates 5e, TCXO, SAW and RTC oscillators in a small and light package, which can speed up time to market and reduce product development risk. CSR believes that its advanced energy-saving mode can greatly save battery power and is an ideal module for wearable and portable personal navigation applications.
Felix Marchal, Chief Product Officer of Telit ’s Wireless Communications Solutions Division, said: “Jupiter SE868-V2 has outstanding performance in all positioning tasks and is very suitable for navigation applications that require high reliability. By adopting CSR ’s SiRFstarV With the 5e solution, we can create a quick and easy upgrade path for our Jupiter JF2 GPS module customers so that they can update to the latest and most powerful multi-constellation receiver version on the market. "
SiRFstarV 5e provides various functions to improve accuracy, improve TTFF and save battery power, and ultimately achieve a better user experience. These features include:
-InstantFixTM Extended Ephemeris (EE)-Let devices without wireless connection (such as cameras, etc.) solve the problem of slow initial positioning. 5e can predict EE automatically 3 days in advance locally, and for networked devices, it can also support server-based EE, with GPS for 31 days and GLONASS for 14 days.
-Direct battery connection-The GNSS chipset can be directly connected to a lithium battery for power supply, thereby reducing system cost and improving power efficiency. By integrating a power management unit (PMU), system-level power consumption and eBOM costs can be reduced.
-Flexible design, which can optimize the cost of the solution-the design of 5e is very focused on the implementation of the solution to reduce the size and power consumption. For example, UART and SPI flash drive levels are 1.8-3.3v, so no level shifters are required and implementation flexibility can be improved.
-Intelligent design-5e's design is optimized for low-power battery-powered equipment. For example, in asset tracking applications, the 5e engine can intelligently determine the time to try to acquire satellite signals according to the surrounding environment, thereby greatly saving battery power.
Dave HunTIngford, Marketing Director of CSR Positioning Products, said: "SiRFstarV 5e devices enable our customers to choose a high-performance solution that provides a seamless navigation and positioning experience for end users of any application. Telit is optimistic about the potential of SiRFstar 5e, It was selected for its own Jupiter SE868-V2 module, which itself reflects the strong positioning accuracy advantage of the solution. "
SiRFstarV â„¢ 5e offers the best size 0.4 mm pitch wafer-level chip scale package (WLCSP) and 0.5 mm pitch ball grid array (BGA) for low-cost PCB applications.
We adopt the advanced technology imported from Europe, patented technology, specialized software to optimize the design for33kV cast resin Dry Type Transformer. The core is made of cold-rolled grain-oriented silicon steel sheet which cut in step-lap by GEORG Germany TBA core cutting lines and laminated by the method of fifth-order step-by-step stacking technology, enabling the no-load performance of the core to improve greatly. The epoxy resin from American HUNTSMAN is adopted for the windings which casted in the vacuum resin casting machine imported from HEDRICH, Germany. The winding material ensures good permeability, no bubbles occur, which leads to minimum partial discharge. The HV and LV winding mate with each other tightly, which ensures solid strength of structure and capability to withstand short circuit and vibration. Under normal service condition, the service life of dry type transformer is 30 years. No crack will form on the surface of transformer winding due to temperature variation as long as the transformer runs under normal service condition.
