Trimble has introduced its new ultra-low power mini Global Positioning System (GPS) receiver-the LassenTM SQ module for mobile devices. With major advancements in performance, power consumption and size, the Lassen SQ module enables system integrators to add GPS capability to a mobile device with minimal impact on its size or battery life.
In today’s wireless world, adding new functionality and finding ways to reduce power and size for mobile, battery-powered applications are key. Many GPS receivers offered on the market today consume 500 milliwatts or more of power. Trimble’s Lassen SQ is a power saving module that even in continuous operation requires only 100 milliwatts. For example, two penlight batteries can power the module for more than 40 hours of continuous operation–that’s 10 times longer than the average cell phone’s continuous talk time. The Lassen SQ’s ultra-low power gives developers flexibility to achieve significant reductions in power consumption when adding GPS capability.
In addition to power consumption, adding GPS capability to a mobile device also meant sacrificing the device’s size. Now, with the Lassen SQ module’s postage-stamp size (~26mm x 26mm) form factor, integrators can easily fit GPS functionality into a variety of mobile products including cell phones, PDAs, digital cameras, notebook and tablet computers, data recorders, in-car navigation and vehicle tracking systems as well as portable instrumentation devices.
The Lassen SQ is a high-performance GPS module. It incorporates Trimble’s FirstGPS™ technology along with a powerful microprocessor in a miniature form factor for a complete position velocity and time (PVT) solution. The highly integrated module is a miniature board containing a GPS hardware core based on Trimble’s Colossus RF ASIC and IO-S digital signal processor (DSP) design and a 32-bit RISC CPU. The module offers onboard data storage in flash memory for complete processing capability.
The Lassen SQ module is compatible with active 3.3 VDC antennas; Trimble provides three models depending on the application-an ultra-compact embedded antenna, a compact unpackaged antenna or a compact packaged antenna with a magnetic mount for moveable installation.
