Making your own drone with GNSS click

A project on hackster.io uses GNSS click to build a semi-autonomous drone. The click plays its part as a GPS receiver.
Read the whole tutorial to see the necessary code, GPS and IMU sensors wiring and more.
The next installment of this tutorial will teach you how to add motor control to the device so that the drone can take flight and fulfill its purpose.
You can start with the video, to see the half-done drone in action. Don’t expect to see it flying yet, it still needs a motor. But what you can see is GNSS click locating the device on google maps.
Better coverage with both GPS and GLONASS satellites
GPS, GLONASS, and Galileo are the three main parts of the GNSS system. At any time there are six to twelve satellites above the horizon that can be used to calculate a position. A GNSS receiver needs at least four satellites to get the necessary information: latitude, longitude, and altitude. The simple conclusion being that the more satellites there are, the more accurate the results will be.
The latest GPS satellite in orbit weighs around 1,400kg. That is the weight of an average midsized car. Imagine a Toyota Prius moving through space, at the speed of several kilometers per second.
GNSS click carries the L86 module from Quectel, with an integrated patch antenna. It has a UART interface and runs on a 3.3V power supply.
With its ultra low power consumption of 20mA in tracking mode, it fits the IoT field like a glove.
For more information on the GNSS click, see the product page.
You can also take a look at the GSM/GNSS 2 click if you want to add mobile connectivity to your project as well.

Combining the power of GSM and GNSS — GSM/GNSS click
Posted by Lana Vulic on 13 January 2017 05:32 PM
Have you ever considered what kind of technology is necessary for you to know your exact location just by looking at your phone? Well, it takes at least four satellites orbiting the planet to be in view of a receiver to calculate such a precise position.
Thankfully, we have a new click that does all the hard work for you, GSM/GNSS click combines all the GSM functions with GPS and GLONASS location tracking.
GSM/GNSS click carries the MC60 quad-band module from Quectel. When the click is connected to a GPS antenna it can receive precise coordinates from orbiting satellites. The click has an onboard Bluetooth antenna and the MC60 module supports Bluetooth 3.0.
Send texts, share files over Bluetooth or find out what your location is. GSM combined with GNSS allows you to both communicate with other devices over the cellular network and have asset tracking as well.
Add the GSM/GNSS click to your suitcase and program it to notify you with an SMS of its location every 2 hours. Never again will you have to worry about your luggage being lost at some airport. Track anything else you would not like to lose track of.
Quectel’s EASY™ technology
EASY™ or Embedded Assist System allows the MC60’s GNSS engine to automatically calculate and predict orbits using the ephemeris data (up to 3 days) when the power is on.
GPS + GLONASS
GPS is not the only positioning system orbiting our planet. Although it has the most satellites, 33 to be exact. There are other systems in place as well. The second one, when it comes to the number of satellites is the Russian GLONASS — Global Navigation Satellite System, and it has 24 satellites.
Using a module that combines both these systems, like the MC60 module, featured on GSM/GNSS click, provides more accuracy and more stable results.
One obvious advantage that GLONASS has over GPS is that it has satellite systems meant for high latitudes, where GPS does not.
