This condition will continue until the computed velocity rises above 1.

When the vehicleвЂ™s velocity falls below a threshold, the position and heading are frozen, and velocity is set to zero. The company's GPS technology currently goes into a variety of devices including a child locator, which is a mobile phone for children that helps parents locate them. The SiRF documentation says 'Static navigation is a position filter designed to be used with motor vehicles. SiRF started operations in 1995 with the aim to take GPS to mass markets by decreasing the cost of the technology, power consumption and device size.

Kisel has designed a variety of radios, including those for Wi-Fi, WiMax, and Bluetooth wireless standards, he added. 'Multiple radios are going to be a very critical part of what we are doing,' Chadha said. SiRF's overall strategy is to integrate into its GPS chips some of the functions that are currently available on mobile devices, but often require separate chips. For example, information on the car navigation system can be updated with real-time information like traffic information from a mobile phone.

'We found that mobile phones and some other devices that were shipping with our GPS chips also had Bluetooth, and it made sense to provide a lower cost, lower power, and size-optimized alternative to having two separate systems,' Chadha said.Д«luetooth will also help connect various devices that use GPS. I am guessing it is TTL logic compatable. Reading a data sheet indicates that it can be changed to Sirf binary output. Availble pins are Vcc and Gnd (5v), TXA, RXA, TXB, RXB, and Boot. The first products based on the SiRFLinkI chip are expected by the end of this year, according to Chadha. The GPS still works and locks so I am thinking - a spare GPS, why notThe GPS is based on a discrete Sirf GPS2e LP-7450 chipset, which I think defaults to 9600 baud NMEA.

The chip uses a Bluetooth software stack from Impulsesoft, and a Bluetooth radio from Kisel Microelectronics AB, a Swedish company SiRF acquired last year that specializes in RF (radio frequency) integrated circuit design. Arduino + Parallax GPS module (PMB-648 SiRF) Radioshack was having a huge clearance and was selling the Parallax GPS module for only 10 I saw this as an opportunity to experiment with a GPS and use it for a robot or some kind of tracking device in the future. SiRF of San Jose, California, also introduced its SiRFLinkI, a chip that combines GPS and Bluetooth capabilities. The acquisition is in line with SiRF's strategy to add wireless connectivity and other functions to the GPS chips that it sells to mobile phone, automotive, mobile computing and embedded markets, said Kanwar Chadha, SiRF's founder and vice president of marketing. Ltd., a Bluetooth-embedded software company in Bangalore, for US$15 million in cash and stock. SiRF Technology Holdings Inc., a vendor of chips and software for GPS (global positioning system) applications, announced Thursday that it has acquired Impulsesoft Pvt.
