OpenFly for SatNav — Navigation-pretrained initialization

This checkpoint is designed for use with SatNav, the continuous-state vision-and-language navigation platform for satellite maps. The SatNav OpenFly integration uses it to predict the next action from a language instruction, three RGB observations, and recent action history.

Model

Starting checkpoint: IPEC-COMMUNITY/openfly-agent-7b
Training data: SatNav-v0.1 offline trajectories
Training: 1 epoch, full-parameter fine-tuning, learning rate 2e-5
Context: 3 RGB frames and up to 16 previous actions
Action format: stop, forward, left, and right

Repository name

openfly-satnav: OpenFly adapted to SatNav
continue: navigation-pretrained initialization from the OpenFly Agent checkpoint
1ep: trained for one epoch
actcompact: predicts compact textual action labels
sample: the following fields describe trajectory-step sampling
hk7: keeps the first seven action steps
fs3: keeps every third step in a consecutive forward run; turning steps are kept
stopx2: repeats each stop sample twice
stopw0: labels only the terminal step as stop
tail5: keeps the final five steps before stop
stoph1: uses one history variant for each stop sample
hist16: includes up to 16 previous actions in the prompt
lr2e-5: uses a learning rate of 2e-5

Reference Results

Results reported in the SatNav paper, baseline comparison, row OpenFly (navigation-pretrained).

SR, SPL, and OS are percentages. NE is measured in meters. Steps is the average number of executed environment actions, including turns and stop.

Split	SR (%)	SPL (%)	OS (%)	NE (m)	Steps
Test Seen (`val_seen`)	21.1	21.0	38.1	163.07	57.85
Test Unseen (`val_unseen`)	17.1	16.9	34.9	196.90	65.56

Usage
