Taoglas, a provider of Internet of Things (IoT) and GNSS antenna products, has released two new GPS certification testing services for Google and its device partners. The services are required for devices to meet Google’s new Street View auto-ready standard. Auto-ready certification distinguishes 360-degree cameras that deliver accurately positioned 360 video, even at high speeds. Taoglas worked with Google to develop the performance requirements, as well as the test methodology used to establish a basic minimum level of GPS receiver performance. The services are available at any of Taoglas’ design centers and labs in the United States, Ireland, Germany and Taiwan. Compact wireless devices such as digital cameras with built-in GPS receiver systems contain complex electronic systems that can emit unwanted RF signals that can impact radio receiver performance. The effect of this RF noise can be combated with critical design decisions like the antenna, low noise amplifier, filters, and transmission line choice and implementation. Taoglas’ new services will help device manufacturers objectively measure real-world performance to understand any GPS performance issues with their products. With this information, product manufacturers will know if their performance is optimized and will meet or exceed user expectation for the application at hand, as well as how it compares with their competitors. “Google Street View provides people with a 360-degree view of the world, and to enable these services, we require highly accurate location data,” said Charles Armstrong, product manager at Google. “By working with Taoglas to establish a standardized compliance process, we’re helping device manufacturers understand our requirements for GPS performance and quickly deliver products that match and exceed those high performance standards.” Taoglas is offering two levels of certification testing: Street View Auto-Ready Conformance Testing (GSA.31) provides a quick verification of minimum performance (in a pass/fail manner) required to achieve Street View certification. Taoglas uses its GPS constellation simulator and anechoic chamber to verify that radiated tracking and acquisition sensitivity meet a minimum performance standard at 15-degree intervals in one hemisphere. From these test results, manufacturers will be able to clearly see if the device’s GPS is performing adequately for basic location capabilities. The condensed period needed to run this test provides device manufacturers the best value to answer the question, “Is the GPS working optimally?” A street view image of Guatemala.

Taoglas uses its GPS constellation simulator and anechoic chamber to measure radiated tracking and acquisition sensitivity at 15-degree intervals in one hemisphere. These optional tests provide more insight into how well a device performs, providing absolute receive sensitivity performance data. Testing results for both services include suggestions on next steps to resolve identified issues. “This partnership with Google to deliver GPS testing solutions for Google Street View compliance is an excellent example of how we’re working successfully with the world’s biggest companies to delivering high-quality, reliable antenna solutions,” said Dermot O’Shea, co-CEO of Taoglas. “By certifying their products through Taoglas, device manufacturers will also be able to take advantage of Taoglas’ deep RF expertise, achieving success quickly and reducing time to market.” “Street view” of the Ambrym Volcano, Vanuatu.
