![]() ![]() Satellite signals, Wi-Fi signals, and light, are electromagnetic waves of different frequencies that are invisible to the naked eye.įor example, light will reflect when it meets obstructions. Outdoors, the weather is fine but there are high-rise buildings nearby, although satellites can be found, but the positioning effect is still poor, that is because the signal will be reflected. Indoors, the cement roofs and walls directly block signals, GPS mode cannot be used. If the signal is obtained, but weak, that is because the GPS signal is very susceptible to interference. The only way you can do is to move to other area. If you can't find it, you can't receive the signals at this location. You stand at this position and turn on the drone. Just turn on your drone and the GPS module inside works, and then search for satellite signals. There are many satellites all over the world. They send signals to the ground every moment. The time transmitted to the receiver (the GPS module inside the drone) takes long, so the number of stars on the remote is slowly increasing. The satellites are transmitted at the same time. In addition to this, the position of each satellite is different, and the distance is different from yours. The download speed will be very fast in the good weather and the open area. For example, the weather is not good, there are clouds blocking, the download speed will be slow. ![]() Why does it takes time to search for GPS signal? When the drone downloads the data (it means the search is successful, preferably more than 8 stars), the drone can know its position and time, and fly steadily without offset. If we want to know its current position, we have to determine which orbit the satellite move round the earth and download the orbit data. The satellite flies in the sky, and the position of each moment is not fixed. Holy Stone adopt GPS/GLONASS system, because these two are the most mature, and with two at the same time, the positioning effect is more precise.Īs shown in the picture, the earth we live in is surrounded by many satellites. At present, the four major satellite positioning systems in the world are: Global Positioning System (USA) BeiDou Navigation Satellite System(China) Global Navigation Satellite System(Russia) Galileo satellite navigation system(Europe). Of course, it was launched by the earth person. The first thing to know is where the GPS signal comes from? Then questions are coming:ġ.Why does it takes time to search for GPS signal?Ģ.Why is the GPS signal weak/unsearchable?ĭo you want to know these? Today, I will tell you all about it. If you use Progressive Leasing and want to purchase early call 87.HS100 and HS700 are GPS drone which must get GPS signals to fly steadily outside, and use smart features. ![]() Progressive Leasing's early purchase options cost more than the retailer's cash price (except 3-month option in CA).
