It is managed by Ordnance Survey. It provides access to a stable, national coordinate reference system (through downloaded GNSS data) that allows highly accurate location to be determined using suitable equipment, and is used in surveying, construction and precision agriculture industries, among other uses.
Surveying — Survey-Grade GNSS receivers can be used to position survey markers, buildings, and road construction. [6] These units use the signal from both the L1 and L2 GPS frequencies. Even though the L2 code data are encrypted , the signal's carrier wave enables correction of some ionospheric errors .
A surveyor uses a GNSS receiver with an RTK solution to accurately locate a parking stripe for a topographic survey. Real-time kinematic positioning (RTK) is the application of surveying to correct for common errors in current satellite navigation (GNSS) systems. [1]
Vehicle navigation on a personal navigation assistant Garmin eTrex10 edition handheld. A satellite navigation device or satnav device, also known as a satellite navigation receiver or satnav receiver or simply a GPS device, is a user equipment that uses satellites of the Global Positioning System (GPS) or similar global navigation satellite systems (GNSS).
GNSS systems that provide enhanced accuracy and integrity monitoring usable for civil navigation are classified as follows: [5] GNSS-1 is the first generation system and is the combination of existing satellite navigation systems (GPS and GLONASS), with Satellite Based Augmentation Systems (SBAS) or Ground Based Augmentation Systems (GBAS).

The number of childfree women is at a record high: 48 percent of women between the ages of 18 and 44 don’t have kids, according to 2014 Census numbers. The Huffington Post and YouGov asked 124 women why they choose to be childfree.
Durability. For me, when I think of Lands' End, I always think "forever" because, as a kid, my mom would always buy me a Lands' End coat a couple sizes too big so I could get at least a few years ...
In geodesy, GNSS is used as an economical tool for surveying and time transfer. [4] It is also used for monitoring Earth's rotation, polar motion, and crustal dynamics. [4] The presence of the GPS signal in space also makes it suitable for orbit determination and satellite-to-satellite tracking. Examples: GPS, GLONASS, Galileo
