What's New¶
Nov 26, 2025¶
Effective December 1st, monthly credit allotments for ASF’s HyP3 On Demand processing service will be reduced to 8,000 credits per user per month. Due to NASA budget reductions, we have had to reduce our On Demand processing capacity, and can no longer support the same volume of product generation as we have in the past.
HyP3 has generated over 12 million analysis-ready Sentinel-1 products since its public debut in October 2020, made possible through generous funding from NASA. We now generate about half a million products a month on behalf of more than 1,000 users.
We remain committed to our mission of making remote sensing data accessible. We will continue to balance processing demand against our available budget and adjust quotas as necessary to ensure that we can support as many users as possible.
If you are impacted by this reduction in processing capacity, consider these alternatives:
For Sentinel-1 InSAR applications:
- Consider using our Burst InSAR workflows. These allow generation of interferograms over a smaller geographic area than a full Sentinel-1 SLC, with a corresponding reduction in the number of processing credits required for a full InSAR time series analysis.
- Consider requesting interferograms at a coarser resolution (20x4 looks), which consumes fewer processing credits than finer resolutions (10x2 or 5x1 looks).
- ARIA Geocoded Unwrapped Interferograms (GUNW) are archived and available for many tectonically active regions, potentially eliminating the need for on-demand processing.
For Sentinel-1 RTC applications:
- Consider the OPERA RTC-S1 dataset available through ASF. This data product includes near-global coverage from 2016 to present at 30-m pixel spacing, potentially eliminating the need for on-demand processing.
- For applications requiring a finer resolution, consider requesting On Demand RTC products with 20-m pixel spacing, which consumes fewer processing credits than 10-m pixel spacing while still providing much more detail than 30-m products.
For applications requiring more than 8,000 credits worth of processing each month:
- Consider ASF’s recently-launched HyP3+ service, which allows users to purchase additional processing credits.

HyP3+ is now available!
For users who need more processing than the 10,000 credit limit allows, ASF now hosts HyP3+, a user-supported version of HyP3 that allows you to purchase as many credits as you need.
