ACCURACY OF EMBEDDED GPS RECEIVERS FOR RECREATIONAL USE

Advances in the GPS receiver and various other technologies have made navigation affordable and suitable for a variety of applications. Unlike in the past when civilian GPS appliances were designed primarily to solve engineering tasks providing fast and accurate measurements, GNSS of today serves hundreds of low-cost consumer applications, ranging from geotagging, sportsmanship, social networking, outdoor navigation and others. Although many personal navigation applications focus primarily on service availability rather than measurement accuracy/integrity, finding the right balance between the two and bundling it in a user-appealing value-formoney context has been a critical success factor. The paper presents results from field tests undertaken to assess positional accuracy of recreational GPSenabled devices including smartphones. The results showed minor differences in the positional accuracies achieved by the smartphones tested. The corresponding accuracies of the evaluated Garmin recreational receiver demonstrated much higher accuracies. The devices were hence compared with respect to their unit prices, portability and versatility, and recommendations were given as to their possible uses.
