Coherence in GNSS: A Critical Consideration When Testing and Simulating

Nonetheless, you will require using modernized GPS equipment that has the technology to output signals that accurately simulate the antenna electronics of the GPS receiver. One of such equipment is the wavefront generator simulator with which the jamming source can now displace the signals in coherence with the expected reception pattern of the antenna.

Why in Coherence?

Coherence is a critical factor whenever you are testing global navigation satellite systems. That is so because using extended integration times will reduce the noise when transmitting navigation messages. You will require coherence considering the power consumption requirements, noise conditions, signal acquisition times, and odds of signal detection of your GPS equipment.

Coherent Integration to Increase Accuracy

The longer your GPS coherent integration time is, the higher the chances of having better signal detection and fewer false alarms are. However, these extended integrations reduce the acquisition time since the GPS receiver will linger, searching for the transmitted signal. Nonetheless, if you have set your GPS in a tracking mode, you can use coherent integration to increase the accuracy of signal transmission and reception.

Tracking Weak Signals

Indoor environments pose a significant risk in reducing the carrier-to-noise ratio of signals that are penetrating through the building’s walls. Low CNR values present GNSS receivers with the challenge of having highly-optimized signal acquisition sensors with advanced tracking functions to get accurate results.

Using GNSS receivers indoors no longer has to be a limitation that hinders your application of GPS in your industry. With the right jamming simulator, you can determine how best to optimize signal displacement to be in coherence with your expected reception pattern of the GNSS antenna. Moreover, modernized GPS will provide you with higher chances of achieving accurate indoor positioning.

The Importance of GPS in Everyday Life

a couple travelingGlobal Positioning System or GPS is a navigation system. It uses satellites in space put there by the US government starting in 1973. It was originally for military use, but the government allowed civilians to use it in the 1980s. It can map and track anything on Earth with a GPS device.

However, it has some limits. The receivers need to be in a line of sight with at least four satellites to work. Bad weather and loss of power can mess it up. Companies that make and sell GPS devices have to perform GPS simulations regularly to make sure these are accurate.

This last one is important because many people rely on GPS in everyday life. A company that fails to do this will get a bad reputation. Here are three of its most important uses of GPS.

Traveling

The most common use of GPS is in travel. You probably use GPS through a navigation app on your mobile phone, or a device built into your car or boat working as receivers. It works very much like a paper road map, except it is much simpler to use.

It also has added features. It can tell you the shortest or fastest route to where you want to go, and when you are likely to get there. Also, it can also tell you about traffic conditions, accidents, and roadwork. If you are looking for a particular place, you can use GPS to find it for you.

Tracking

GPS tells you the location of a particular receiver. This can be useful in keeping track of property, people, or pets. This is especially useful if you have children, wayward pets, or employees that spend most of their time in the field.

All you need to do is to put a GPS receiver on what or whom you want to track and add its ID to your GPS device. Many businesses use GPS to keep track of inventory.

Health sensing

An important innovation in GPS is its use in wearable health sensors. It monitors the condition and location of people with medical issues. The device detects any sign of trouble and instantly sends a report to medical and emergency personnel.

This can help save their lives. This is especially important for people who live alone or with non-medical caregivers.

GPS has many uses in everyday life. It is very useful for many people. However, its usefulness is dependent on its accuracy. Regular GPS simulation testing is essential to make sure it sends the right information in real time.
