2. Turn on your blue dot in the app

Once you're in the app and on your project, activate your GPS location using the arrow icon in the right toolbar 

1.  Tap the arrow icon in the right toolbar It turns green when active. Your blue dot appears on the map at your current location. 
2.  Watch for the accuracy ring A larger blue circle surrounds your dot — this is your accuracy ring. The smaller the ring, the more accurate your GPS signal. It tightens as your phone locks onto more satellites. 

3. Move around and the dot follows you Your blue dot updates in real time as you walk the project. The station reading at the bottom of the screen updates with it.

3. Read your station and offset

The mini station finder sits at the bottom of the map screen. It shows your current station, offset, and alignment at a glance.

1.  Glance at the bottom bar Your station, offset, and alignment name are always visible here while GPS is active. 

2.  Tap the bar to expand the full station finder The expanded view shows your full station and offset reading, the alignment name, and the copy icon to copy your station to clipboard. 
3.  Tap the copy icon to copy your station Copies the full station and offset to your clipboard — useful for pasting into a flag note or a message. 

4. Switch or lock an alignment

If your project has multiple alignments — a mainline and a frontage road, for example — OnStation will snap to whichever one you're physically closest to. You can also manually lock to a specific alignment or jump to a station on a different one.

1.  Tap the alignment name in the station finder Opens the Select Alignment sheet. Your current alignment is highlighted in orange. 

2.  Lock or Jump Tap Lock to pin your station reading to that alignment regardless of where you're standing. Tap Jump to move the map view to a specific station on that alignment. 

5. Switch between STA, MM, LL, and LRS

In the expanded station finder, tabs at the bottom let you switch how your location is displayed. Not all options are available on every project — it depends on what your project's design file includes 

• STA
• MM
• LL
• LRS

6. Switching to a different project

To move to a different project, tap the OnStation logo in the top left corner of the map. This takes you back to your project list where you can select a new one.
