MicroInfinity Carna® has two types of CNSs (Car Navigation Systems). MicroInfinity Carna-GPodin® uses internal information of the car and MicroInfinity Carna-GPtrion® use no external device. MicroInfinity Carna® provides continuous position and heading angle of the car in any environment. MicroInfinity Carna® fuses the information from the MEMS (Micro-Electro-Mechanical System) based inertial sensors and GPS (Global Positioning System) to calculate the current position and attitude of the car. Using the optimized navigation filter, MicroInfinity Carna® offers precise position information of the car in urban and rural area as well as tunnel and underground parking lot.

  Two types of evaluation kits are available for testing and developing of car navigation product with the MicroInfinity Carna^® products. The purpose of the MicroInfinity Carna^® Evaluation Kit is to provide a platform on which the MicroInfinity Carna^® GPS/DR(Dead Reckoning) receivers may be run and on which new firmware development may take place. The needs of the project and the technical expertise of the user usually determine which of two types of evaluation kits should be chosen.
This dual port, MicroInfinity Carna^® Evaluation Kit is suitable for field and laboratory testing of the MicroInfinity Carna^® GPS/DR(Dead Reckoning) receivers. The first DB-9 connector is the main RS-232 port and the second DB-9 connector is dedicated to RTCM-104 Differential GPS (DGPS) correction signal input. On-board LEDs indicate power on, TXD/RXD. The kit consists of a MicroInfinity Carna^® Evaluation Kit : 12 channel GPS receiver; active GPS antenna, power adaptor, CD and standard serial cable. The providing CD includes monitor software and evaluation kit documentation.

  Telematics is a new evolving generation of technology with communication and location capabilities. The communication technologies for telematics are mature, but the location technology has much room for development. GPS (Global Positioning System) is commonly considered sufficient, but no location information is provided if the GPS fails, surprisingly this happens frequently in urban cannon area, under roadside trees, tunnel, underground parking lot, and under an overpass. MicroInfinity telematics solutions provide precise and seamless location information in tough environment.
MicroInfinity helps setup the telematics terminals and services with sophisticated navigation technology.

1. Dead Reckoning (DR): MicroInfinity has developed GPS/DR/Map-Matching since 1996. The DR configurations are either gyroscope and odometer or gyroscope and accelerometer to obtain angular velocity and linear velocity (acceleration). With the precise sensor calibration and estimation algorithms, MicroInfinity can provide location information when GPS fails or shows inaccurate locations due to surrounding factors. Additionally, DR can record the profiled motions of the car in case of accident or emergency call. MicroInfinity announce analysis tools of the recorded motions of the car in 2003.


2. Map Matching (MM): People want to know where the restaurant, gas station, stores are located. The geographical informational features appeared in the map and, in most cases, the car is shown on the mapped road (off-road situations occur very rarely). With compact and thin numerical map, MicroInfinity MM indicates where the car is on the map.


3. Global Positioning System (GPS): GPS often considered to be unaffected by vendors and technology used, but MicroInfinity has found that the performance and characteristics of GPS varies by vendors and technologies. Every GPS performs well when the satellites are in a good configuration and the users are in open spaces. More realistic performances occur in less-than-ideal situations such as in urban cannon area, under the roadside tree, on heavy rainy or snowy days. These environments can result the multi-path, attenuation and non-line of sight of GPS satellite signals. MicroInfinity GPS solutions are robust to these conditions and use DR for enhanced tracking of GPS satellite signals.


4. GPS/DR/MM: MicroInfinity fuses DR, MM and GPS to sustain the location information in any conditions. The ultimately optimized Kalman filters and navigation algorithms give accurate, robust, and well-defined location information.
