Marine Navigation High Gain GPS Antenna with TNC Connector
Q:What is an RTK antenna?
A:RTK is short for real time kinematics. A GPS receiver capable of RTK takes in the normal signals from the Global Navigation Satellite Systems along with a correction stream to achieve 1cm positional accuracy. GNSS includes satellites from GPS (USA), GLONASS (Russia), Beidou (China), and Galileo (Europe).
Q:What is the difference between GPS and RTK?
A:Unlike traditional GPS systems, which rely on data from satellites alone, RTK GPS systems use additional data from a nearby base station to improve the accuracy of the GPS data. This can provide positioning data that is accurate to within centimeters, making it ideal for a wide range of applications.
Q:The picture is real product?
A:Yes,all product pictures are real product.
Q:If stock quantity is not enough from link, how to do?
A: Contact/Leave message to us, we will reply and help check exact stock within 12 hours.
If go to bulk ordering, usually lead time 10-15 days.
Q:when I go to bulk several items, and find shipping cost is different, how do I do?
A: Shipping cost depends on unit weight, but if you find shipping cost very high,
Contact/Leave message to us, we will check whether shipping cost can be reduced.
Q:How can I get commercial invoice for company finance?
A: Contact/Leave message to us,leave billing address, we will send PDF version there.
Q:Is the antenna has different length cable or connectors?
A:Yes, can be custom-made, Contact/Leave message to us, we can quote for you.
Q:Is GLONASS better than GPS?
A:The 2 systems also differ somewhat on accuracy. GLONASS position accuracy is 5-10m while GPS is 3.5-7.8m.
Therefore, GPS outweighs GLONASS in accuracy as lower error numbers are better.
Q:Should you use GPS with GLONASS?
A:Actually only gps should do its job in case satellite reception is perfect.
The combination with another system will improve accuracy when the signal gets weaker.
Q:Does GPS work without an antenna?
A:GPS (Global Positioning System) systems work by receiving signals from satellites.
