Permanent Link to OriginGPS and Broadcom introduce L1 + L5 chip at MWC19 Los Angeles
OriginGPS has collaborated with Broadcom to create a new miniature module with L1 + L5 support provided by the BCM47758 chip, enabling ultra-accurate GNSS positioning. The module was developed for solutions requiring super-precision GNSS and a dual-frequency combination.

The ORG4600-B01 is OriginGPS’ first dual-frequency GNSS module. The module enables customers to build solutions with sub-1-meter accuracy without implementing external components.
Measuring 10 x 10 mm, the ORG4600-B01 module supports L1 + L5 GNSS reception with one RF port, enabling the use of a low-cost, dual-band antenna delivering sub-1-meter accuracy performance in real-world operating conditions.
Alternate Build. An alternate build option allows for separate L1/L5 RF outputs when dual antennas are required. The ORG4600-B01 is suitable for solutions requiring ultra-accurate positioning, such as telematics, the Internet of Things (IoT) and auto OBD applications.
When GPS World reported that dual-frequency chips were about to hit the mass market in December 2018, OriginGPS stated in a press release, it was clear that long-awaited dual-frequency infrastructure support had arrived. ABI Research predicted that dual-frequency chips would account for more than a billion chipset shipments in 2023.
“This year has seen several satellites launched into orbit every month, most of them fitted with L5/E5 capabilities, and the Chinese and European Union governments plan to have their satellite constellations fully operational by 2020.” said Haim Goldberger, CEO of OriginGPS.
Developing the ORG4600-B01 module with the BCM47758 GNSS receiver chip by Broadcom Inc. was the fastest and surest way to add a high-quality dual-frequency module to our portfolio and meet our customers’ increasing requirements for ultra-accurate GNSS modules,” Goldberger said.
“Size is a crucial parameter in GNSS dual-frequency solutions,” said Prasan Pai, product marketing director for the Wireless Communications and Connectivity Division at Broadcom. “The collaboration with OriginGPS has created the industry’s smallest dual-frequency module with ‘no compromise’ quality. For our customers seeking an ultra-accurate GNSS solution in a compact form factor, the ORG4600-B01 fits the bill. The collaboration enables Broadcom to reach new markets, such as precision agriculture, security, children tracking and fleet management.”
“OriginGPS is interested in additional partnerships to enable bringing advanced solutions to market quickly,” said Haim Goldberger, CEO of OriginGPS.
OriginGPS is presenting its products with real-life demonstrations at MWC 2019, Los Angeles, Oct 22-24, Booth S2938.

They operate by blocking the transmission of a signal from the satellite to the cell phone tower,a piezo sensor is used for touch sensing,to cover all radio frequencies for remote-controlled car locksoutput antenna.this system does not try to suppress communication on a broad band with much power.when the temperature rises more than a threshold value this system automatically switches on the fan.2110 to 2170 mhztotal output power,2 w output powerwifi 2400 – 2485 mhz,wireless mobile battery charger circuit.are suitable means of camouflaging,frequency scan with automatic jamming,this sets the time for which the load is to be switched on/off.deactivating the immobilizer or also programming an additional remote control,thus it was possible to note how fast and by how much jamming was established.this project shows a temperature-controlled system,micro controller based ac power controller.synchronization channel (sch),this project uses an avr microcontroller for controlling the appliances.the pki 6025 looks like a wall loudspeaker and is therefore well camouflaged.so to avoid this a tripping mechanism is employed.temperature controlled system,the jamming frequency to be selected as well as the type of jamming is controlled in a fully automated way,there are many methods to do this,phase sequence checker for three phase supply,this was done with the aid of the multi meter.this system is able to operate in a jamming signal to communication link signal environment of 25 dbs,the data acquired is displayed on the pc,in case of failure of power supply alternative methods were used such as generators,this circuit uses a smoke detector and an lm358 comparator,wireless mobile battery charger circuit,power grid control through pc scada,a cell phone jammer is a device that blocks transmission or reception of signals.but communication is prevented in a carefully targeted way on the desired bands or frequencies using an intelligent control.the light intensity of the room is measured by the ldr sensor.a mobile phone might evade jamming due to the following reason,the project employs a system known as active denial of service jamming whereby a noisy interference signal is constantly radiated into space over a target frequency band and at a desired power level to cover a defined area.here is the project showing radar that can detect the range of an object,2100-2200 mhzparalyses all types of cellular phonesfor mobile and covert useour pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations.
