NAVI-Orbital: First In-Orbit Demonstration of a Zero-Shot Vision-Language Model for Autonomous Earth Observation
Quick Answer
This paper shows that NAVI-Orbital, deployed on a Low Earth Orbit spacecraft, achieved the first in-orbit demonstration of the Gemma 3 vision-language model for autonomous Earth observation, achieving 88.16% accuracy on the AID benchmark.
Quick Take
This system processes imagery onboard, enabling semantic compression and reducing the need for extensive downlink bandwidth.
Key Points
- NAVI-Orbital uses Gemma 3 for autonomous multi-modal inference onboard.
- Achieved 88.16% accuracy on the AID benchmark with 7,960 curated images.
- Utilizes natural-language dialogue for re-tasking via plain-English prompts.
- Demonstrated feasibility of running foundation models on satellite-class edge computers.
- Enables semantic compression of Earth observations to optimize bandwidth.

Source Excerpt
As Earth Observation data generation outpaces downlink bandwidth and human-in-the-loop processing, a widening gap has emerged between onboard collection and actionable ground intelligence. This paper presents NAVI-Orbital, a software system deployed on a Low Earth Orbit (LEO) spacecraft. On April 16, 2026, NAVI-Orbital achieved what is, to the authors' knowledge, the first in-orbit demonstration of a performing autonomous multi-modal inference entirely onboard. NAVI-Orbital

HOBA (Hierarchical On-policy Bidding Agents) is a novel hierarchical reinforcement learning framework that enhances online advertising bidding systems by improving adaptability and reducing hyperparameter tuning costs. It utilizes a for hyperparameter inference, a SARSA agent for expert model selection, and a dynamic expert pool for bid execution, achieving a +3.6% increase in target cost during large-scale deployment and outperforming state-of-the-art baselines on AuctionNet.
