u-blox 6 GPS Modules
Data Sheet
Abstract
Technical data sheet describing the cost effective, high-performance
u-blox 6 based LEA-6 series of GPS modules, that bring the high
performance of the u-blox 6 position engine to the industry
standard LEA form factor.
These versatile, stand-alone receivers combine an extensive array of
features with flexible connectivity options. Their ease of integration
results in fast times-to-market for a wide range of automotive,
consumer and industrial applications with strict size and cost
requirements.

1.5 Assisted GPS (A-GPS)
Supply of aiding information like ephemeris, almanac, approximate previous position and time, satellite status
and an optional time synchronization signal will reduce time to first fix significantly and improve the acquisition
sensitivity. All LEA-6 modules support the u-blox AssistNow Online and AssistNow Offline A-GPS services9 and are
OMA SUPL compliant.
1.6 AssistNow Autonomous
AssistNow Autonomous provides functionality similar to Assisted-GPS without the need for a host or external
network connection. Based on previously broadcast satellite ephemeris data downloaded to and stored by the
GPS receiver, AssistNow Autonomous automatically generates accurate satellite orbital data (“AssistNow
Autonomous data”) that is usable for future GPS position fixes. AssistNow Autonomous data is reliable for up to
3 days after initial capture.
u-blox’ AssistNow Autonomous benefits are:
Faster position fix
No connectivity required
Complementary with AssistNow Online and Offline services
No integration effort, calculations are done in the background
For more details see the u-blox 6 Receiver Description including Protocol Specification [2].
1.7 Oscillators
LEA-6 GPS modules are available in Crystal and TCXO versions. The TCXO allows accelerated weak signal
acquisition, enabling faster start and reacquisition times.
1.8 GALILEO
When GALILEO-L1 signals become available, LEA-6H receivers will be capable of receiving and processing them
via a firmware upgrade. The ability to receive and track GALILEO satellite signals will result in higher coverage,
improved reliability and better accuracy.
9 AssistNow Offline requires external memory on the host for LEA-6S, LEA-6A, and LEA-6T-0
