Data delivery will be at burst level. Each burst will generate a product.

Naming convention:

- Track + Orbit Direction - 4 chars (3 + "A"/"D")

- Burst - 4 chars

- Swath - 3 char ("IW"+1)

Data will be delivered using a partition of the territory in square tiles, obtained in projection **ETRS89-extended/LAEA Europe (EPSG: 3035**). Each tile will be 100km x 100km wide. The tile's upper left corner coordinates will name the tile. Given the width of the tile, the upper left coordinates will be the points having this form: (XX00000, YY00000), and the relative tile identifier will be EXXNYY. The tiling system, in particular, is the same used in EGMS.

Naming convention:

- Tile identifier - 6 chars (see example below)

- Component: 1 char ("V" or "E")

In this case, a single dataset per track will be delivered.

In this case, InSAR data generated per each of the considered CSK frames will be distributed employing a track-specific grid (i.e., once generated, the PS data is cropped using a grid aligned with the satellite track - see figures below).
57-
58-
A unique ID will identify each grid cell.
59-
60-
NOTE 1: PS/DS products will be cropped using the grid, not the input SAR data. The PS calculation will still be performed at the frame level.

NOTE 2: the case presented below constitutes an example of the grid we will generate and distribute. We will likely define a grid with larger cells.
