Telematics Solutions
Providing Previously Unimagined Travel Options
Honeywell magnetic sensors provide key telematic solutions for mobile navigation, position detection, and location based services.
Our magnetic sensors and sensing solutions offer the dead reckoning and pointing elements needed for vehicle and mobile wireless platforms using telematics. Whether you are an OEM or aftermarket telematics equipment or subsystem provider, we have the low-cost platform position sensing solution for you. By sensing the earth's magnetic field, we are able to provide accurate heading information. When combined with platform tilt, acceleration and/or Global Position System (GPS), a complete customer information system is created for safety, mobility and convenience.
With headings provided by magnetic sensors, map displays and direction/mapping applications are more useful than with GPS alone. Basic position information by Telematics Service Providers can be combined with Traffic Avoidance, Time to Destination and Weather / Road Hazard data to give customers travel options previously unimagined. Honeywell sensors not only provide earth's magnetic field detection and relative direction, but also contain patented features to cancel vehicle stray fields that can confound lesser magnetic sensors.
As a subset of Telematics, Location Based Services (LBS) take advantage of user location and heading to create opportunities for customer information inquiries and geographic based marketing. LBS "pull" opportunities use customer data mining, creating a location/direction profile and filtering local LBS provider directory of products/services as the customer travels towards their destination. For example, a traveler on a freeway making a request to update a map display for upcoming McDonald's restaurants and corresponding exit ramp numbers. LBS "push" opportunities provide customers LBS information in the form of advertising, traffic alerts, weather conditions and tourist attractions. An example would be state/national provided information on upcoming scenic overlooks and local parks.
The HMC Family of Magnetic Sensors for Telematics Honeywell offers several magnetic sensors for earth's magnetic field sensing. The HMC1021 and HMC1022 family of magnetoresistive sensors are miniature components that include integral offset strap coils for each sensitive axis to null out vehicle chassis magnetic stray fields. Used singly or in combination, the HMC102X magnetic sensors create compass headings for two-axis or three-axis (tilt-compensated) direction finding. The +/-6 gauss linear range and 20 gauss saturation threshold provide plenty of range while preserving magnetic resolution below a milli-gauss.
For very compact handheld and windshield mount applications, the sub-miniature HMC105X family of magnetic field sensors preserves precious circuit board real estate in several package styles. An example is the HMC1052L in a 3 x 3 x 0.9mm LCC package, perfect for low-cost platforms in tight spaces. The HMC1051, HMC1052, and HMC1053 have the same magnetic field sensing characteristics as the HMC102X family.
For drop-in mobile/vehicle telematics solutions, Honeywell also offers the a line of two and three axis digital compass ICs and HMR compassing solutions.
