https://devzone.nordicsemi.com/f/nordic-q-a/77893/gps-signal-lost-in-a-car-with-window-cling-filmDear Devzone, We are testing GPS of our products based on nRF9160. When we test in one car, the GPS signal is lost when the device is put inside this car. This situation does not happen in other cars. This car seems to have a cling film on windowsen-USTelligent Community 13Wed, 28 Jul 2021 04:27:33 GMThttps://devzone.nordicsemi.com/thread/322126?ContentTypeID=1Wed, 28 Jul 2021 04:27:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b4ad34ba-0087-4620-b239-c8a3281bf2f3Ngoc Nguyen<p>Dear Marjeris,</p> <p>Thanks for your answer,</p> <p>Best regards,</p> <p>Ngoc Nguyen</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/321993?ContentTypeID=1Tue, 27 Jul 2021 09:16:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7900eb88-e16b-4205-8fd5-736245dc0084Marjeris Romero<p>Hi,</p> <p>After a quick google search I did find multiple car forums where people have complained about bad GPS reception with tinted heat-absorbent windshields or heat-arbsorbent glass, so this seems to be a common problem for GPS signals.</p> <p>A car will act as a Faraday cage for RF signals, so ideally the GPS antenna should be place outside the car, as you need a clear vision of the sky to make GPS work.</p> <p>Best regards,</p> <p>Marjeris</p><div style="clear:both;"></div>
