# Emlid Studio

## Before you begin 

### Download Emlid Studio

Emlid Studio can be downloaded at the link below

{% embed url="<https://emlid.com/emlid-studio/>" %}

### No TIFF Imagery

Emlid Studio is only able to process and update metadata tags of JPEG photos. The tool currently isn't able to process monoband TIFF photos from 6X Series Sensors.

### Metadata Restrictions

Emlid Studio only will only change some of the metadata of the tagged imagery.

Latitude and Longitude values are updated with the PPK solution, but there are no updates to metadata fields to indicate this change:

* "GPS Processing Method" still identifies data as a 3D fix, not PPK
* "GPS Horizontal Position Error" still identifies 0.4691 m accuracy, while this should be centimeter level accuracy.
* XMP tags, including  "GPSXYAccuracy" and "GPSZAccuracy" are not updated.

Tags do not consistently update the reference frame:

* "Altitude" is updated to ellipsoid (WGS84) rather than Geoid height (EGM96).&#x20;
* “Map datum” and “Altitude reference” still identifies data in EGM96 Geoid reference.

## Processing

### Open Emlid Studio

Select Drone Data from the drop down.

{% endstep %}

{% step %}

### Upload Files

Begin adding files in the Processing Section. These files include:

* The gnss.ubx file from your Sentera Sensor.
* The observation file from your base station or reference network.&#x20;
* The MRK file from your Sentera Sensor.

{% endstep %}

{% step %}

### Drone - Gnss.ubx&#x20;

Add the gnss.ubx file from your Sentera sensor. This file will be found in the flight folder. You can drag the file or navigate to it through your file explorer.

Once the gnss.ubx file is added, Emlid Studio will generate a new rinex\_gnss folder with gnss.25O and gnss.25P files. These new files are automatically added to Emlid Studio in the Drone and Navigation fields.

{% endstep %}

{% step %}

### Offload Base Station Files

Files can downloaded from the Emlid Base Station webpage (Reach Panel) or from the Emlid Flow App.

View the article below for instructions on offloading the files.

{% endcontent-ref %}
{% endstep %}

{% step %}

### Base - Observation File

Add your base station observation file. This can be from a Base Station such as the Emlid Reach RS2 or from a CORs network.

You can drag the file or navigate to it through your file explorer.

Click save to update your settings.
{% endstep %}

{% step %}

### Process&#x20;

Click process and wait for your results.&#x20;

After processing the Geotagging section will open. The gnss\_events.pos file was generated from the processing and automatically populates the Timestamps field.&#x20;
