OneSky Analytics in DroneDeploy

Our DroneDeploy apps put safety-of-flight analytics into the hands of pilots planning their commercial flights today!
 

GPS FORECAST APP

OneSky's GPS Forecast app presents users with 1-hour-out predictions for the number of GPS satellites available in a flight's range and the level of accuracy (HDOP) those satellites will likely provide.

OneSky's Altitude Profiler app displays a flight's predicted height above the ground throughout the planned route, helping pilots understand and adjust their "above ground-level" (AGL) altitude profile. 
 

 

GPS FORECAST APP

OneSky's GPS Forecast app lets DroneDeploy users quickly understand the health and availability of GPS prior to flying.  The forecast is provided for 1 hour from the current time and predicts the maximum number of satellites that can be expected as well as the Horizontal Dilution of Precision (HDOP) of the navigation solution provided by those available satellites.

 

 

How Does It Work?

Once you have installed the OneSky GPS Forecast app from DroneDeploy's App Marketplace, you simply click the OneSky app from any flight plan to reveal the GPS forecast for that flight.  

You will see a series of charts showing a 1-hour forecast of GPS health & availability metrics.

 

What Does It All Mean?

Satellites Available :  This graph will indicate how many satellites your receiver should be able to "see" in the sky from any position along the flight's route.

HDOP :  Given the number of available satellites and their positions relative to your receiver, the HDOP (Horizontal Dilution of Precision) will reveal how "accurate" the latitude and longitude positioning data is likely to be. Values under 1 are ideal, while values over 2 are not recommended for precision navigation. 

Our analytics are generated by continually updating and predicting the location of each satellite in the GNSS constellations (e.g., GPS, GLONASS, and GALILEO). Determining which satellites you can access involves accurately predicting the motion of all satellites relative to your receiver on Earth, while accounting for other factors, such as minimum elevation angles and number of receiver channels.

 

ALTITUDE PROFILER APP

OneSky's Altitude Profiler app provides insight to any flight plan's expected height above ground.  Flying relative to a takeoff location is quite common, but the reality of terrain changing below the aircraft is a real-world consideration which can be modeled by OneSky analytics.  This helps any pilot quickly understand and anticipate what their 'above ground level' (AGL) altitude profile should look like along their planned flight path. 

 



How Does It Work?

Once you have installed the OneSky Altitude Profiler app from DroneDeploy's App Marketplace, you simply click the OneSky app from any flight plan to reveal the Above Ground Level (AGL) altitudes along the flight path.  

The corresponding chart will show the altitude of the aircraft relative to the ground below it from start to finish of the flight plan.

 

What Does It All Mean?

Terrain Profile:  The app will display a graph which shows the expected altitude of the aircraft relative to the ground below it at any position along the flight plan.  Since most consumer level drones normally display the altitude the aircraft has climbed 'relative' to where it took off, it is important to also understand that while the aircraft is moving along its planned flight, the actual altitude with respect to the ground beneath it can change significantly.  The Altitude Profiler is a great way to plan for and understand these types of terrain changes.  

Our analytics are provided by hi-resolution terrain data for the entire globe.  Our Terrain Server product makes it possible to catalog & manage terrain data sets while providing an analytical API for querying terrain related results such as this.  For more information about the data involved, click here.
