Ensuring Elderly Safety with Advanced Mini GPS Tracking Solutions

If you plan to upload maps, look for a model with plenty of storage space. Also, consider a device that connects to multiple global satellite systems (GNSS) like Garmin’s GPSMAP 67i and offers a combination of GPS, paj-gps, Galileo, QZSS, and BeiDou.

Some models offer extra features such as a barometric altimeter and digital compass, but the most important factor is a navigation device that provides quality Portable GPS mapping and position tracking.


GPS devices work by locking onto satellite signals. They then save a series of points, which software connects into a path (remember: straight lines are always the shortest distance between two points). Newer units often have options for how frequently they check in; more frequent polling can improve accuracy but can drain the battery and fill memory faster.

GPS accuracy is impacted by many factors, from the quality of the device to your environment. Physical obstructions like tall buildings or canyons interfere with satellite visibility, slowing the signal and decreasing accuracy. Thick tree cover also attenuates signals, as they bounce off the leaves and branches. In these conditions, GPS accuracy can drop to three to five meters, but advanced GPS systems can improve on this with technology like DGPS, which uses ground-based reference stations to correct the signal and boost accuracy to jaw-dropping levels of up to 1 centimeter per second. Combined with A-GPS (which augments the GPS with cell network data), these devices offer unparalleled positioning speed and accuracy.

Battery Life

Many smartphones have GPS capabilities, but their small displays are not optimized for recreational navigation and their battery lives are limited. Handheld GPS devices have larger displays and longer battery life, making them more suitable for hiking, fishing, geocaching, camping, and other outdoor activities. Many feature rugged designs that resist thermal stress, water, and shock. Some also include extras like internal electronic compasses, more memory, and cameras.

Traditionally, handheld GPS devices have used AA batteries, which are inexpensive, long-lasting, and easy to replace in remote areas where access to stores is limited. However, many manufacturers now offer rechargeable batteries as a more practical alternative. Depending on your specific needs, you may also want to consider how much weight you can comfortably carry when choosing a GPS. Handheld GPS devices can range from a few ounces to more than a pound, with higher-end units such as Garmin’s Montana series featuring more advanced features and a tank-like design that meets military specifications for heat, water, and shock.

Waypoints and Tracks

Waypoints are locations marked on the GPS screen or in mapping software by the user. They have at least two dimensional coordinates (latitude and longitude) and can also be given a name, symbol or icon. They may also have an elevation. Some of them, called “via points” in Garmin products, may be intermediate locations within a calculated Route path.

A Portable GPS also allows you to save your location at regular intervals, called tracks. The result is a series of dots on the map, showing your path as you move. You can follow these tracks on the screen of your GPS, using a compass or directional arrow, to get from one point to another. You’ll need to consult your GPS user manual for specific instructions on how to mark a track. You can also set a track recording time interval such as every second or every meter. Some of these Track Points can have additional data such as heart rate or wind speed.


Smartphones have been eroding the market for standalone GPS devices and with good reason. These pocket-sized wonders have a much wider range of features that include a camera, internet connectivity, weather apps, and smart notifications, as well as GPS functionality.

GPS uses satellite signals to track and record timing and position information. Satellites circle the earth twice a day in precise orbits, transmitting unique signals that GPS receivers can decode and use to determine the user’s location.

A GPS device’s signal can be disrupted by the user’s location, nearby objects and even buildings. To mitigate these issues, GPS units can be equipped with multi-band GNSS support. This technology allows the receiver to connect on two frequencies, increasing time-to-first-fix performance and accuracy in challenging conditions. GPS units with multi-band GNSS capability are usually denoted as such on this website. The most commonly used GPS is the United States Global Positioning System, followed by Russia’s GLONASS, China’s BeiDou, and the European Union’s Galileo systems.
