TIM-LR

OEM GPS Module

ANTARIS® Positioning Engine

 TIM-LR GPS Module For new designs, we recommend
the TIM-4R instead.

Overview

The TIM-LR is an ultra-low power sensor-based dead reckoning GPS module suitable for passive and active antennas. The combination of the ANTARIS GPS positioning engine and the Enhanced Kalman Filter EKF™ algorithm provide precise navigation in locations with no or impaired GPS reception, for example tunnels, indoor car parks and deep urban canyons. Deviations in navigation caused by multipath effects, as commonly observed in cities with densely populated high-rise buildings, belong to the past. The TIM-LR is the ideal solution for high-volume applications requiring a cost-effective and tightly integrated product that fulfills 100% road coverage requirement.

The leading ANTARIS® GPS Engine provides excellent navigation performance under dynamic conditions in areas with limited sky view like urban canyons, high sensitivity for weak signal operation without compromising accuracy, and support of DGPS and multiple SBAS systems like WAAS and EGNOS. The 16 parallel channels and 8192 search bins provide fast start-up times. The aiding functionality accelerates start-up times even further.

Sensor-based GPS receivers supplement the GPS information with an incoming signal from a gyroscope (turn rate sensor) and from odometer pulses to do dead reckoning navigation through periods of GPS outages. Depending on the quality of the available GPS signals, the EKF algorithm from u-blox computes the next positions accurately by using an automatically weighted average of the GPS and sensor inputs.

Compared to standard GPS receivers, the SBR-LS provides significant advantages in following application areas:
  • In-vehicle navigation systems:
    Accurate and timely driver directions in tunnels, underpasses, urban canyons and parking houses. Very efficient elimination of multipath effects prevents position errors resulting to misleading navigation advices.

  • Automatic vehicle location / fleet management:
    Accurate and up-to-date position of the entire fleet is reported anytime and anywhere, including tunnels, covered driveways and indoor parking. The increasing requirements for efficient logistics and security will be met.

  • GPS-enabled road pricing:
    Ability to manage different rates for different routes, tunnel and bridge passages, urban charge zones, support distance-dependent rate plans and automatic billing of indoor and outdoor parking.

  • Homeland Security:
    Continuous position determination of dangerous goods and accurate direction of emergency vehicles.
