Various kinds of satellite navigation systems are present in the market today. They offer distinct positioning accuracies. They all work by using satellites to know precise locations of things on Earth.
Global Positioning System (GPS): GPS is the first GNSS to be developed and, until recently, the only one in operation. At least 24 satellites orbit the planet at 20,200 kilometers. They transmit signals to ground receivers located all over the world. The U.S. Department of Defense developed it to help track the location of military personnel and equipment. The system was opened up for civilian use in 1980.
Global System for Mobile Communications (GLONASS) is a Russian GNSS. It uses at least 27 satellites to cover the whole world. GLONASS satellites travel in slanted orbits over the equator so that they never stay over the same point on Earth. The system was developed in the 1980s but wasn't fully operational until 2007. Today, it's an important backup to GPS and provides global positioning to at least 98% of the world.
Galileo is a GNSS being built by the European Union and European Space Agency. Galileo is designed to provide more accurate positioning for civilian use. It aims to reach global coverage with at least 30 satellites by the end of 2020. Galileo will provide better location service to people in Europe and beyond, especially in urban areas where satellite signals can be blocked.
BeiDou: China's BeiDou is also under construction and will soon provide global coverage. It is currently operating over China with at least 10 satellites in its first phase, called the "short-message communication" system.
Galileo is helping to guide heavy machinery at construction sites so the machines dig, lift, and move exactly where planned. This limits human error and speeds up projects.
Farmers use GNSS to automate planting seeds in straight lines, ensuring crops grow evenly. This maximizes yields and minimizes waste.
In Australia, miners rely on GNSS to track the locations of trucks transporting ore to ensure efficient transport without delays.
Surveyors use GNSS to measure land precisely, aiding cartographers in creating accurate maps for development planning.
GNSS assists paramedics in quickly locating accident victims to provide timely medical aid where required.
In the energy industry, GNSS tracks the movement of drilling rigs and other equipment. This helps managers ensure projects stay on schedule without excess expenditure.
GNSS supports ship captains in navigating safely, even in challenging weather, which contributes to the reliability of maritime operations.
Telecoms use GNSS to synchronize the placement of cellphone towers and other devices, bolstering network reliability for users.
Positioning Accuracy
Sinocnn's GNSS provides precise location measurements within a few centimeters or meters, depending on the required settings, such as real-time correction.
Real-Time Data
Sinonness GNSS gives location updates and measurements within seconds, which is optimal for industries that need quick and accurate data, such as construction and mining.
Multiple GNSS
It's important to note that the SinoGNSS works with multiple satellite systems, such as GPS, GLONASS, Galileo, and Beidou. This improves the accuracy of the system and makes it possible to receive signals even when obstructions are blocking the satellites' views.
Durability
The receivers are rugged, built to withstand harsh environmental conditions, including water, dust, and extreme temperatures. This makes the GNSS suitable for outdoor and construction applications.
Post-Processing Capability
Many Sinoness models allow users to record data for later analysis and correction, enhancing accuracy for land surveyors.
Long Battery Life
Sino GNSS users report extended battery life, making it possible to work longer without charging the device in intense work environments.
Installation: To set up a Sino GNSS device, the user first needs to download the app for their phone or tablet and set it up for the phone or tablet. Phone or tablets users should ensure they have a compatible phone or tablet because the GNSS device pairs with it. The user then has to turn on the GNSS and go to the Bluetooth settings on their phone or tablet to pair the devices. The user also needs to enable location services. Most phones and tablets require the location services to be enabled to use GNSS. After that, open the app so the GNSS device syncs with it. The app should recognize the Syno GNSS device, displaying the satellite data.
Using the Product: GNSS users get their positions by linking satellites in the sky to a receiver on Earth. For accurate measuring, the receiver picks signals from at least four satellites. The satellites send their locations and the exact time they sent the signals. The receiver uses this information to figure out its position through a math process called trilateration. By measuring how far each satellite is from the receiver, the receiver can determine where it is on a map.
Maintenance: To maintain Sino GNSS devices, users should regularly inspect their devices for signs of damage from prolonged use in harsh conditions. This includes checking for water or dust inside the device. Users must clean the devices, especially the antenna, frequently to get rid of debris that may interfere with satellite signals. Users should update the device software to ensure it runs optimally with the latest features. Users should store their GNSS in a protective case when not in use to avoid damage.
For surveying instruments, satellite signals must be very steady for smooth functioning. That's because small errors can cause major difference in land measurements. If a receiver isn't able to lock onto signals from at least four satellites steadily, it may struggle to determine locations correctly. This makes steady signals important for accurate work in land surveys.
Since survey work can take several hours, many surveyors like using a receiver that can maintain good accuracy while locked onto just a few satellites as the sky changes. Under thick clouds, in deep canyons, or near tall buildings, it's vital that a surveyor's receiver keeps tracking signals from as many satellites as possible. Every satellite helps the receiver pinpoint its location more exactly.
GNSS receivers can track signals from different satellite systems, including GPS, GLONASS, Galileo, and BeiDou. By utilizing this full range of satellites, the receiver captures more signals in challenging environments. Picking a GNSS unit that can track all these satellite systems improves the receiver's performance for accurate land surveys.
Ascending and Descending: GNSS satellites are placed in two main groups, ascending and descending, as they circle the Earth. This formation helps the satellites cover every area of the globe as they move over the poles. Receiving satellites from both groups improves tracking and accuracy during surveying work.
Signal Strength: Surveyors choose receivers that can capture satellites' signals from far away with good strength. Strong signals enhance accuracy, particularly in challenging environments like forests or urban areas.
Trimble GPS: The survey instrument industry leader Trimble employs cutting-edge satellite technology in its GNSS receivers. This legacy anniversary company control signal processing increasing precision at locations.
Shielding from Excess Heat
Many GNSS receivers are sensitive to temperature. Keeping them in the shade prevents overheating that could damage internal parts or cause errors in location data.
A1: The clients update the software regularly, clean debris off the GNSS, and inspect the device for damage.
A2: A client can expect the device to last for four years with proper care and routine maintenance.
A3: The customers should protect the GNSS from the sun, rain, and dust. They should also clean the device and check for damage often.
A4: Using a GNSS that connects to multiple satellites increases accuracy because the receiver can capture more signals at once. More satellites improve precision, especially when working in tough environments like forests or cities.
A5: Picking a GNSS that can track signals from different satellite systems, like GPS and GLONASS, enhances accuracy by giving the receiver more signals to work with. More signals boost performance indoors and out of obstacles.
