LEA-6
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.

LEA-6 - Data Sheet
1 Functional description
1.1 Overview
The LEA-6 module series is a family of stand-alone GPS receivers featuring the high performance u-blox 6
positioning engine. These versatile receivers feature an extensive and flexible range of functionality, connectivity
and cost savings options. LEA-6 modules maintain the industry standard 17.0 x 22.4mm form factor of the
LEA-5 series and have been designed to allow simple migration. Their ease of integration results in reduced costs
and short time to market for a wide range of automotive, consumer and industrial applications.
The 50-channel u-blox 6 positioning engine boasts a Time-To-First-Fix (TTFF) of less than 1 second. The dedicated
acquisition engine, with over 2 million correlators, is capable of massive parallel time/frequency space searches,
enabling it to find satellites instantly. Innovative design and technology suppresses interference sources and
mitigates multipath effects, giving LEA-6 GPS receivers excellent navigation performance even in the most
challenging environments.
LEA-6 allows simple integration with u-blox wireless modules.
1.2 Product features

1.14 Dead Reckoning (LEA-6R)
LEA-6R receivers supplement the GPS information with an incoming signal from a gyroscope (turn rate sensor)
and odometer pulses to do dead reckoning navigation through periods of poor GPS reception. Depending on
the quality of the available GPS signals, the LEA-6R uses an algorithm specially developed by u-blox in order to
compute the next positions accurately by using an automatically weighted average of the GPS and sensor inputs.
This provides precise navigation in locations with no or impaired GPS reception, for example in tunnels, indoor
car parks and deep urban canyons.
The LEA-6R is a low power dead reckoning GPS receiver module. The LEA-6R is the ideal solution for applications
requiring accurate, reliable positioning, all of the time.
The LEA-6R includes a front-end LNA.
1.14.1 Supported peripheral components (LEA-6R)
The LEA-6R supports the following peripheral components:
A/D converters with SPI interface
Linear Technology, LTC1860, 12-bit A/D converter
Table 7: Supported peripheral components
digital temperature sensors with SPI interface
National Semiconductors,
LM70, precision: 10 bits plus sign
Gyroscopes should at least meet the requirements listed below:

Recommended operating temperature range
Table 8: Required Specifications for Gyroscopes
Specification
5.0 V ± 0.25 V
2.5 V ± 0.4 V
25 mV/°/s ± 5 mV/°/s
± 60°/s to ± 125°/s
± 0.5% (Full scale)
–40°C to +85°C
Gyroscopes with a sensitivity of lower than 20 mV/°/s may work but the performance will be degraded. For this
reason u-blox does not recommend using gyroscopes with a lower sensitivity.
For implementation details as well as a list of supported gyroscopes that u-blox is currently aware of, or for more
information about Dead Reckoning and other special features of the LEA-6R refer to the LEA-6/NEO-6/MAX-6
Hardware Integration Manual [1] and the u-blox 6 Receiver Description including Protocol Specification [2].
