I’m trying to develop a new method for locating the origin of the shots. The method consists in:
1- Obtain the distance from a specified location of the first shot estimate the delta time to synchronize the times of the shot sequence.
2- Then at any other location create a grid where will be tested the specified shot delta time correction subtract from the time from the first calculation.
3- Then this delta time in absolute value is converted to meters for each receiver.
4- Finally, the medium value of error in meters is plotted on the grid.
My results are presented below:
the grid is 4x4 meters with 0.08m between the grids.
Assumptions:
1- Shot 1 came from Crooks Muzzle.
2- Grid center for shot 2 to 8 is Crooks Muzzle geolocation
3- Grid center for shot 9 is the SWAT officer geolocation.
4- Bullet times used from @offtheback:
5- Geolocations from my study.
Bullet 2:
Bullet 3:
Bullet 4:
Bullet 5:
Bullet 6:
Bullet 7:
Bullet 8:
Bullet 9:
Conclusions:
Considering a medium error of 1.4m all bullets from 1 to 8 came from the same location.
Bullet 9 came from the SWAT officer in the middle with a medium error of 2.5m.
Could not evaluate bullet 10 because there is too much error in the report time.
The conclusions are the same of @greg_n work. With different time data then Greg and with a different method.
I did not define the location of the shooter yet. But will work on it. But is for sure that all first 8 bullets came from the same place.
edit: inverted the grid 7 with 9.
