What is GLONASS And How It Is Different From GPS

GLONASS is an acronym, which stands for Globalnaya Navigazionnaya Sputnikovaya Sistema, or Global Navigation Satellite System. GLONASS is Russia’s version of GPS (Global Positioning System).
Here is a table of specs comparing GPS vs GLONASS

Advantage of GLONASS over GPS (GLONASS Vs GPS)

There is no clear advantage other than accuracy over GPS. When used alone GLONASS doesn’t have that strong coverage as GPS has, but when both used together certainly increases accuracy with coverage. And it is more useful in northern latitudes as Russia started GLONASS originally for Russia.
The accuracy is an advantage of GLONASS with up-to 2 meter of accuracy. GPS + GLONASS allows your device to be pin pointed by a group of 55 satellites all across the globe. So when you are in a place where GPS signals are stuck like between huge buildings or subways, you will be tracked by GLONASS satellites accurately.

Best Rugged solid toughed durable Smartphone 2017

Image
For those with a demanding job or lifestyle with constant exposure to environmental hazards, a rugged smartphone with military-grade protection may be the best option. A rugged smartphone is also a smart choice to use as a second phone when traveling. Ruggedized smartphone models meet military testing standards for protection against shock, water, dust, extreme temperatures, and vibration. They are waterproof and can withstand submersion in shallow water for a limited time. When using a rugged smartphone, keep in mind that while these phones have been tested to military specified standards, care should still be taken as glass screens are not immune to cracking, and drop test ratings do not guarantee you will always have the same results. Here are the best rugged smartphones for 2017 that are available unlocked. The following phones will work on GSM carriers like AT&T and T-Mobile but not CDMA carriers like Sprint and Verizon.

LG V20 Quad Dac makes AKG, Beets or Boom Sound to think once again

Image
This B&o Headphone with the combination of LG V20 makes a new bench mark which makes all sound producers to think once... LG has been really pushing forward in the audio game lately, bringing the first 32-bit DAC to smartphones with their G5 ‘Friends’ accessory, while the G5 already had an in-house 24-bit DAC. Now they are back with the V20, with what they claim is the first mobile Quad DAC . I’m going to dive in below to see if the Quad DAC is just a buzzword marketing-term, or if it is actually useful and noticeable in everyday use. Regardless of the outcome, the LG V20 is a pretty awesome phone.

Why one plus Dash charging Technology is soo fast..!

Image
From a broader perspective, Dash Charge on the OnePlus  is not all that different. Just like other quick-charging solutions, it starts by delivering a massive amount of power to the battery, gradually reducing the rate of charge as the cell is filled up. Where it sets itself apart, however, is in the way power is being sent from the charger to the phone. Quick Charge – the aforementioned technology by Qualcomm, used in recent Samsung, LG, HTC and Moto phones – applies higher voltage to increase the flow of power. Dash Charge, on the other hand, uses greater current. Both solutions get the job done, but they come with a few notable strengths and weaknesses.
