# Pulsar Timing at the Deep Space Network

## TL;DR

This paper reports on the recent upgrade of the Deep Space Network's Goldstone antenna with pulsar timing capabilities, achieving high-precision timing residuals and initiating baseline observations for millisecond pulsars.

## Contribution

It introduces the first operational pulsar timing system at DSS-14 and details plans for similar systems at other DSN antennas.

## Key findings

- Achieved < 100 ns residuals for pulsar B1937+21
- System successfully enables pulsar searching and timing
- Baseline TOA measurements are underway

## Abstract

The 70-m DSN's Deep Space Station antenna 14 (DSS-14) at Goldstone has recently been outfitted with instrumentation to enable pulsar searching and timing operation. Systems capable of similar operations are undergoing installation at DSS-63, and are planned for DSS-43. The Goldstone system is the first of these to become operational, with a 640 MHz bandwidth stretching from 1325-1965 MHz. Initial results from the pulsar timing pipeline show short-term residuals of < 100 ns for pulsar B1937+21. Commissioning obsefvations at DSS-14 to obtain a baseline set of TOA measurements on several millisecond pulsars are currently underway.
