Cost, accuracy, handling and functionality are some of the key factors that distinguish these two GPS grades.
GPS is everywhere — just look around and you will find GPS in your friend’s phone, your cousin’s smart watch, your uncle’s car and maybe his boss’s shoes or jacket. Given the large number of smart devices easily available in the market today — some of them costing barely $100 — selecting the right product can be tricky. However, the good news is that these devices come under the recreational GPS grade and are in no way even close to the professional grade. So, what is the difference between professional and recreational GPS? Let’s find out.
Availability
Recreational GPS is easily available in devices sold at most electronics and sports goods stores. These are e also widely available e-commerce sites. These devices are the least expensive and are generally accurate to within +/- 25 feet (7.6 meters). On the other hand, mapping or survey grade GPS receivers, or simply professional GPS receivers, are sold by high-end and licensed resellers. These receivers are less user-friendly and cost significantly more.
Accuracy
As their names suggest, recreational and professional GPS units are planned, designed and built for different purposes. A recreational GPS unit is essentially designed to get a basic location without the need for very high accuracy. For instance, the GPS on your smartphone often takes you to a building a few meters from your desired location. Even though recreational products are not specifically designed for GIS mapping, they can be used successfully in some applications. Most GIS users need extremely accurate placement of features, often within a meter or less so that data layers can be overlaid and intricate spatial relationships can be determined. Professional or Survey grade GPS are accurate to within a centimeter and are used primarily by professional surveyors. These excel in high accuracy measurements of fixed positions.
Cost
A device with recreational GPS grade is available for anything between $100 and $500. On the other hand, mapping grade GPS generally come in the $1,000 to $3,000 range. The most expensive category of GPS, survey grade, includes devices that cost tens of thousands of dollars. Mapping grade GPS receivers are mostly used by government agencies, researchers and other users who require accurate and dependable coordinate fixes.
Data quality and other factors
The ability to determine the quality of data is provided by professional GPS units, which in a way allow users to control the accuracy of the position points. Through a simple interface, users can establish specific thresholds for acceptable data quality. A user can choose the number of satellites and position above the horizon needed to achieve a certain degree of accuracy. The quality control settings let the user to filter out poor data that may degrade the overall quality.
When shopping for a GPS unit, a user must assess a receiver against his project and GIS application requirements. There are significant differences between recreational and professional-gradeGPS receivers, which are designed and built for different purposes.
Accuracy. As their names suggest, recreational and professional GPS units are planned, designed and built for different purposes. A recreational GPS unit is essentially designed to get a basic location without the need for very high accuracy.
A recreational GPS unit is designed to acquire a location fix quickly without the need for pinpoint accuracy because hikers can find their campsite once they get within 10 meters of it.
It is important to recognize the grades of GPS receivers, namely consumer, mapping, and survey grade, and their ability to accurately map features with or without differential correction.
Mapping grade GPS receivers are most often used by government agencies, researchers, and other users who require more accurate and dependable coordinate fixes than a recreational GPS can provide. 3. Survey grade GPS receivers are the most accurate and the most expensive.
The Garmin GPSMAP 66st is at the top of its class in terms of accuracy and reliability, earning it our top honors. It boasts a powerful quad-helix antenna and reliably connects to more satellite networks with greater accuracy than most other models.
Designed for outdoor recreation activities like hiking and camping, they provide basic latitude and longitude coordinates while plotting points of interest and straight-line routes. Most are accurate within five to 10 meters.
What is the difference between A-GPS and GPS? Assisted GPS, generally abbreviated as A-GPS, enhances the startup performance of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones.
The L1 signal is the oldest GPS signal. It has two parts: the Coarse/Acquisition Code (C/A) and the Precision Code (P-code). The P-code is reserved for military use, while the C/A is open to the public. The L1 signal uses the frequency 1575.42 MHz (source).
A module is an all-in-one digital receiver that, from those signals, calculates the distance of a satellite. It's performance, therefore, is critical in ensuring accuracy. GPS receivers come in a variety of forms: from integrated circuit chips to all-in-one modules.
GPS and Google Maps are completely different things. GPS is a radio that listens to satellites in space and calculates a location. Google Maps is a software application that provides a layout of a map to help you navigate around in a specific location.
Static GPS Baseline – This method is used to determine the coordinates for survey points by simultaneously recording GPS observations over both a known and unknown survey point for at least 20 minutes. The data is then processed to determine coordinates within 5mm accuracy.
A GPS receiver does not transmit any signals, all it does is receive GPS data beamed to earth from GPS satellites. If you can't receive the GPS signals, you can't get your position.
Is military GPS more accurate than civilian GPS? The user range error (URE) of the GPS signals in space is actually the same for the civilian and military GPS services. However, most of today's civilian devices use only one GPS frequency, while military receivers use two.
It offers live traffic and weather, and supports calling via a Bluetooth connection to your phone. In addition, you can use the built-in Garmin voice assist to get directions.
Active GPS receives and amplifies the GPS signal it receives from satellites by sending power to the attached GPS antenna. Active GPS devices will always have a SMA GPS port for an external antenna, which allows for the amplification of the signal. Active GPS will work better in poor coverage areas.
The open road is yours to explore, thanks to RV-specific GPS navigators. Get custom routing, road warnings and a directory of RV parks and services right at your fingertips. Spend less time planning your trip and more time enjoying it.
The purpose of using GPS navigation is to reach a destination point or identifying one's own position in the map. The purpose of tracking is to identify something or someone else's position on a map.
Since its first application to field and team sports in 2006, global positioning system (GPS) technology has been used to detect fatigue in matches, compare intensity profiles according to player position, compare competition skill levels, and identify the most intense periods of play. 1.
